I highly recommend this Captain Disillusion video about color if you want to learn more about color theory: [this video] You may have to watch the video multiple times though, because the information comes out of a firehouse.

For A/V stuff, I went looking for an understanding of how color works in video systems, and ran across this gem from Captain Disillusion: [this video] His whole channel is great, though there's not a ton there, it makes sense given the staggering amount of work that goes into the visualizations of each one.

Short answer: No. We (the majority anyway, as some are colourblind) only perceive lightness, reddish, greenish, and bluish. The brain uses the info and effectively synthesises the image in our brains. Long answer: Colour is a very rabbithole topic but Captain Disillusion has a summary of it ( [this video] ) and Technology Connections has a discussion ( [LINK] ).
