Additive is red green blue, subtractive is red blue yellow.

they're both valid primaries; additive is used for digital screens while subtractive is used for physical mediums

I'm making a poll.

i suppose if we're talking about AvA/M, which is digital, then the primaries would be additive

I'll see

idk if this is what you’re referring to but when people talk about the primary color trio (as in a grouping of characters) they mean red yellow and blue
