Thermal imaging cameras use color to show the relative temperature of objects: cold is purple, moderate is red, and hot is yellow. You`ll see hot and cold spots where insulation is missing, identify where air is getting in or out of your house, and more.
In thermal image, the darker is color the hotter it will be. Accordingly, the purples and dark blue/black indicate cooler temperatures (because they emit less heat and infrared radiation). Some of the cameras take images only in a grayscale, and others use a rainbow color palette.
When examining a thermograph, blue is cold. Green is roughly room temperature. Shades of red and white display areas of inflammation. In a black-and-white thermal image, the darker colors are hotter.
On a colour thermographic display, warmer components or regions will show up as reds, oranges and yellows, while cooler parts will typically be shown as purples and blues (green usually indicates areas that are roughly at room temperature).
Each TI has a maximum range of temperatures between black (cold) and white (hot). In extreme cold (usually less than -40°F) the imager cannot discern a strong enough signal due to lack of heat and cannot discern anything colder. In a very hot scene, the signal will be overridden by noise (saturation).
The Kelvin color temperature scale.

The Kelvin scale is used to measure the color temperature of a light source. The lower temperatures correspond to red, orange, and yellow colors: the warmer spectrum. Higher temperatures correspond to blue or cooler colors.

In thermal imaging, each individual pixel represents a specific temperature data point. These data points are assigned a unique color or shade based on their value, meaning that as the thermal sensor detects changes in heat energy, it will express this change by adjusting the color or shade of a pixel.
Thermal imaging allows you too see an object`s heat radiating off itself. Thermal cameras more or less record the temperature of various objects in the frame, and then assign each temperature a shade of a color, which lets you see how much heat its radiating compared to objects around it.
Indicating the likely temperature of an object by means of colour (red = warm/hot; blue = cool/cold) is common practice in the fields of industrial and interior design in many parts of the world [1]–[7]. Just think, for example, about the colour scheme used on hot and cold taps.
Near infrared wavelengths become visible as red while red wavelengths appear as green and green as blue. Blue wavelengths are shifted out of the visible portion of the spectrum and so they appear as black.
Lighter colors and also whites and metallic substances absorb less of the illuminating light, and as a result heat up less; but otherwise color makes little difference as regards heat transfer between an object at everyday temperatures and its surroundings, since the dominant emitted wavelengths are nowhere near the …
A color temperature of 6500 K is standard for ordinary PC use and for the sRGB standard. Most LCD monitors offer a setting of 6500 K among their color temperature options. If a monitor offers an sRGB mode, setting it to this mode should present no problems.
In passive thermography, the camera is simply pointed at the test piece and from the thermal image a temperature map is constructed. Active thermography involves heating the surface of the object rapidly using an external heat source and observing how the temperature decays with time.
White Hot is the default palette available on nearly every thermal device on the market. In this mode, objects giving off the most infrared energy appear white through the display, while cooler objects giving off less heat are depicted as black.
Thermography is a form of radiography portraying body-surface temperatures, and thermograms are photographic reproductions of infrared rays spontaneously emanating from the body.
Hence, temperature is maximum for white among all the given colours.
Colors at higher temperatures have a cooler color cast to them. Natural light resides on this blue end of the scale. The correct white balance for a scene depends on the color temperature of the light. “In the most basic terms, your white balance tells you that if your whites are off, your color temperature`s off.
Not only does thermal imaging enable detection of cryptic species, it also has great potential to investigate behaviour of nocturnal animals, a task which has often been neglected due to poor visibility10,11.
Thermal imaging ot thermographies works on capturing infrared light emitted from objects, they are unaffected by the visible light. So, yes you can use the thermal imaging camera in daylight.
As the pictures above show, near-IR waves are a different part of the spectrum than visible light. You`ll agree, then, that IR waves do not bring any information about the “color” of objects, they are more likely a “different color” themselves!
Different lightbulbs emit different color temperatures and each can impact a space differently; the higher the Kelvin, the cooler the light, the lower the Kelvin, the warmer the light. And no matter the option you go with, the color temperature will completely impact how a space feels and functions.
Since wood features a heat-isolating property, it is also a real obstacle for heat radiation, and thermal imaging devices usually fail to see through trees. However, it does not make such devices useless when searching for people or hunting or observing animals in the forest-covered areas.
Thermal imaging cameras see in total darkness, producing clear, crisp images without the need for any light. This makes IR cameras excellent instruments for numerous night vision applications.
Since a thermal imaging camera displays a contrasting temperature background of the objects you are observing, it will not show fish with the same body temperature as the water. However, thermal imaging can help you locate fish, but it is not a good idea to use thermal imaging for fishing solely for finding fish.

Q. Do you read Colored Thermographs?
ANSWER : A. Reading a thermograph is possible, though arriving at a diagnosis without a physical exam is not. I’m sure one of the veterinarians at PetCoach can read color thermographs though it would be better for your pet if you had a doctor physically examine your pet after an evaluation of any thermograph. Once this is done, he or she may be able to provide an answer or diagnosis and treatment for your pet.

Q. This morning my dogs urine was the color of weak coffee, she is acting normal and eating fine no fever. She is 1-1/2 years French bull and beagle mix.
ANSWER : A. This color is definitely normal and indicates the presence of pigment, possibly related to blood or liver breakdown products or infection. Highly concentrated urine can appear dark if she has not been well hydrated and if she is in good form otherwise you could increase her water intake by offering flavored water (boil a little chicken or fish and offer her the water; no stock or salted flavors) and monitor for resolution of signs. Any increased frequency of urination, increased color or smell or any discomfort urinating would need investigation. If she is not neutered she may be coming into heat which could result in a colored discharge

Q. Can dog’s and cat’s see in color vision.
ANSWER : A. It was once thought that cats and dogs could only see in black and white but it has since been proven that they are sensitive to green and blue light. So they can see in color but not as well as humans as they are missing the cone that is sensitive to red light. This means that they may have trouble distinguishing between certain colours , a bit like people that are color blind.

Q. What can be given to dogs to stop the brown draining around dogs eyes? I was told tetracycline would work.
ANSWER : A. Eye leakage is normal in some breeds of dogs, especially those that are more “bug-eyed” types. This eye leakage is just normal tears coming from the eye which can stain lighter colored coats. Unless there is an infection it does not need to be treated with antibiotics. Signs of infection usually include drainage that is thick or goopy and is yellow or greenish in color. Dogs with infections may also want to keep the eye closed, or may paw and scratch at it.

For plain tear-staining. Tear-stain wipes can be used around the eyes to remove the stain and bring the coat back to natural color. If infection is suspected, it is best to have your vet take a look at the eye prior to placing any medications in it.

Q. I have a male kitten..white body, orange sots on back and top of head. And one black spot on his tail. His mother is longhair calico. Is he Calico?
ANSWER : A. The Calico is a color classification rather than a breed of cat. Cats of any breed may be able to have a Calico coloration, however Domestic Shorthairs and Medium hairs (your typical house cat) are most likely. Coat color is also linked to a cat’s sex, so females are more likely to be Tortoiseshell while males more likely to be Calico. A Calico coat is one that is a white base with splotches of red, orange, brown and black over it. A Tortoiseshell coat is a black or brown base with white, orange and brown splotches mixed in!

Q. Bowel movement 6 times a day. Stool is soft light brown and white. Sometimes drops of water come out during bowel movement. He seems anxious
ANSWER : A. If your pet is experiencing frequent bowel movements, loose watery stools, or stools that have changed color it is best to contact your local vet. Stools that are watery can indicate many problems ranging from digestive upset, internal parasites or even illness. Color changes in stool can indicate problems such as issues with the pancreas or gallbladder as these two organs contribute enzymes that give stool its brown color. Be sure to bring in a sample (or multiple) of the stool to your vet as this can help them quickly examine it for issues as well as check for common illnesses or parasites.

Q. My dog had very red gums. He is also eating grass. Is this normal?
ANSWER : A. Normal gums on a dog are usually a pinkish color, and can be checked for health by lightly pressing down on the gum until it turns white. When your finger is removed, the color should return within 2-3 seconds. In dogs that are anemic or ill, the gums will continue to be a pale white color for a long period. Gums that are blood red, or appear to be bleeding can indicate a problem such as a bleeding or blood clotting disorder, and can also sometimes indicate ingestion of a poison or toxin causing a bleeding disorder.

If your dog’s gums are actively bleeding or blood red, you think your dog may have ingested something toxic or poisonous, or he has other symptoms of bleeding, lethargy, or illness, it is best to contact your local veterinarian or emergency clinic immediately for treatment.

Q. My dog has a split nail, what should I do?
ANSWER : A. Split or torn nails are very common in dogs, and treatment depends on the level of the tear. If the nail is split above the quik (blood supply to the nail) then it can be safely trimmed back and the torn part removed. You can find the quik in a dog’s nails by looking for a red or pink line in light colored nails, or a darker groove on the underside of dark colored nails.

If the tear is behind the quik or the nail is bleeding, stopping the bleeding with styptic powder or starches such as corn or rice starch can help. It is then best to bring your dog into your local vet to have the nail safely trimmed back. This may require anesthesia or sedation depending on the size of the tear to make the experience less painful for your dog. Your vet may also recommend antibiotics if the tear is large to prevent infection from taking hold until the nail can heal.

Once the torn part of the nail is removed, the nail should be able to begin growing back as normal. Regular nail trims to keep nails short and in shape can also help to prevent tears and splits in the future.
