Hi Allan
When I use pastels, I'm very carefull to avoid yellows,because artificial light have a yellow component. Otherwise the next day in a daylight the painting would be full of yellow tones,unbearable to see.

Hi Adriano,
When we paint in yellow artificial light all the colors will be affected by the light.
The reason that we can see colors at all is that things, and skin, reflects the light that shines on them. In full spectrum daylight you will see a green apple as a green apple, right?
What happens if you paint the green apple in a yellow studio light ?
Two things will happen. Because that the color balance of the light source is weighted toward yellow and therefore contains less red and blue, the green apple will appear more yellowish green and relatively lighter in value than if it was seen in full spectrum daylight.
But it is not only the color that changes when the light is out of balance, it is also the amount of light that is unbalanced. So if you see something that is multicolored, you will see the yellows as lighter than they are and the red / blue as darker than they are.
