What Is Color Temperature?
Lights have a color temperature. This color temperature has nothing to do with the degree of warmth in the weather, but rather it indicates the light color. The color of a light source is described by the color temperature in Kelvin (K).
In the area of white light, LEDs can display different color areas. A light bulb could not do that. So we now differentiate between warm white, neutral white, and daylight. Daylight white is also called cold white.
- Common illuminants have color temperatures in the order of magnitude of less than 3300 Kelvin.
- Warm white is between 2700 Kelvin and 3300 Kelvin.
- Neutral white is at around 3500 to 4500 Kelvin
- Daylight white is at a color temperature of over 5300 Kelvin.
The color temperature describes the color of conventional light sources. So it is difficult to define those using light wavelengths due to their color spectrum. The color temperature is used as an aid.
The color temperature is also defined as the temperature of an ideal black body whose radiation is precisely known as Planck’s radiation formula. The hotter this black body, the shorter the wavelength in which it radiates.
A cold body radiates almost exclusively in the infrared wavelengths. As the temperature progresses, the body first glows red, then yellow, white, and finally blue.
The black body completely absorbs all electromagnetic waves and emits heat radiation when heated. This is used as a comparison to other color values.
As a result, black body reflection radiation is zero. The color becomes whiter as the temperature rises. The black body’s temperature is to be determined as identical in color. The color temperature is most comparable in its light source.

CCT VS CRI
Essentially, light sources are measured using two key factors:
- Correlated Color Temperature (CCT)
- Color Rendering Index (CRI)
Correlated Color Temperature
To determine how cool or how warm a light source is, CCT numbers are used and they are expressed in degrees Kelvin (K).
Usually, light bulbs will range from 2700K (warm, incandescent color) to 5000K or even higher (bright, natural daylight color).
However, it is important to note that CCT cannot assist in identifying an object’s natural color when illuminated.
For example, two fixtures with the same CCT can render colors different from each other. This is where CRI is used to create prominent distinctions.
For household or residential use, 2700K and 3000K are the ideal and most preferred color temperatures.
They create an enticing, warm, and relaxing atmosphere that is these color temperatures are suitable for household applications.
Color Rendering Index
On the other hand, the Color Rendering Index, according to the Light Research Center, helps confirm our perception of color quality.
In simple words, CRI evaluates the light source’s ability to illuminate the color of the object with accuracy.
For Example, if you are seeing an artwork under a light source of 65 CRI, the colors that it will exhibit may not appear realistic or accurate.
However, when you see a similar artwork under a light source of 90 CRI, you will see the artwork’s true colors.
CCT gives us the color of the light emitted from the light bulb by gazing straight at the light source and is instantly obvious to the observer.
Whereas the CRI number doesn’t tell us the light color itself. Instead, it shows us the color of the object to match our perception.
It is not possible to know the CRI value of a fixture just by looking at it. Rather only the approximate or estimated value can be known by seeing a light bulb through naked eyes.
