Color representation is dependent on the lighting and reflective abilities of an area. Daylight is the ideal form of lighting. Daylight is often a yellow-red tinge during the mornings and evenings, and blue-white at noon. The season and weather also have a great impact on the manifestation of color.
To describe light, we use the word color temperature. For instance, steel when heated will glow with a reddish light at a certain temperature. If heating continues, the color changes with the temperature. Higher the temperature, the color becomes lighter and clearer, until reaching a blue-white tinge.
We use the relationship between temperature and color tone to characterize a light source. Color temperature is measured in degrees on a Kelvin scale (K).
Artificial light does not contain all the natural sunlight colors, and therefore, does not reproduce all the color nuances as naturally. Different light sources reproduce different colors.
An incandescent light gives off a warm light whilst light from a tube can be cold and bluish.
There is a standard for the “correct” light. It is called “normal daylight” and has a color temperature of 6500 K. It has the following simple definition: “Light measured at noon, midsummer, on a lightly cloudy day – facing north”. All colors are produced and controlled from this standard.
It is important to be aware of the fact that a small variation in hue or light can alter color reproduction significantly. Consequently, always control color samples in the light in which it will be used. Two similar colors in artificial light can appear different in natural daylight.
