Why computers use RGB instead of RYB? The answer lies in additive vs subtractive colors Stack Overflow

The eye has 3 types of cones (cells in our retina) for perceiving color. Red, green, and blue. The RGB scale won't accurately produce the same phyiscal wavelength as a natural color. However, because of our physiology we can't perceive a difference. This led to to the TriStimulus Theory

Modern CSS also allows colors to be specified in RGBA format. This relates to the previous slides showing the 32 bit encoding or RGB plus and Alpha Channel. W3Schools has an example that is useful for experimentation.

Now for something entirely off-topic: enjoy ...
