What are the primary additive colors?

(Hint, they are not blue red and yellow.)

Red, Green, & Blue - hence RGB monitors

right methos. Bonus, can you name the subtractive primary colors?

Those would be the ones in your printer (well, most home printers) yellow, cyan, & magenta.

yup. but to add on a bonus, many people working with graphics will refer to it cymk I believe, the K standing for black.
