: In RGB, what is each step from 0 to 255 called? From the Wikipedia page on the RGB color model -> Numeric representations: A color in the RGB color model is described by indicating how

@Mendez620

I don't think the increase necessarily refers to a change in color that is the same for each increment. Mac, windows, Photoshop etc each have their own 256 palette and resulting indices. Each individual color, RGB, will have a 0-255 number indicating the relative amount of that color in the "blend"

Interesting question!

I honestly don't understand Luma, Chroma and Chrominance well enough to explain why it is or isn't increased by adding to one or more of the channels. It might increase them, or it might not. I wouldn't know.

It definetly does NOT increase saturation. If we start at (0, 0, 0) and add the same ammount to all channels, the saturation stays zero.

However, adding to a channel increases Brightness.
This is intuitively true, given that the color component on a screen shines brighter for higher values.

It is also well defined, that is,


brightness = (R+G+B)/3
