Light is directly connected with our perception of the world. Massimo Uberti 

The beginning was the light.
On the first day of creation, God created light and darkness.
It was the first differentiation, everything looks grey and dark at night and during the day it is bright and shines in intense colours.
So colour and light belong together. No colours would be perceptible without light.
White light is composed of several colours. When white sunlight is broken down, it consists of the spectral colours red, orange, yellow, green, blue and violet. Sunlight is the perfect white light. In contrast, artificial light can have color gaps. They are therefore also assigned with a CRI value (color rendering index). This value describes the color rendering of an artificial light source compared to sunlight. We see a red tomato red because the tomato only reflects the red light from the white light and absorbs the remaining colours. However, if the artificial light source hardly has a red color range, the red tomato looks more grey and less appetising. So it depends on the composition of the light how we perceive colours.
