Using the additive colour theory, when I add equal parts of red & blue together it is magenta.

But what happens if I add two parts red & one part blue together? Is it still “pure” magenta? Or has it shifted off to the side of red, a little?

Context: I’m creating a game using additive colour theory and I’m a bit perplexed on this one.

Yes, if you change the proportion, the result will change. Have you never mixed crayons or aquarelle paints? In your example two part red + one part blue will end up being something like (depending on saturation) something like #C80064 (or 200,0,100) in RGB
