Explanation

The passage explains that Blue, Green, and Red are fundamental colors because all other colors can be created by mixing them. These are the 'main' or primary colors in the RGB color model. The sentence structure 'However, [X], [Y], and [Z] are the _____ colours, because all the other colours may be got by mixing these' requires 'main' to establish their fundamental nature before explaining why.
