Am I in serious trouble for taking this as a serious question?

I usually implement color as a list of three floating point numbers, typically
in the range of 0..1 where 0 is black, and 1 is as bright as can be.  Typically,
the first number represents red, the second green, and the third blue.

Hypothetically speaking, you can also have numbers greater than 1 (which,
from an implementation point of view, if  you are modeling vision, should tend
to wash out neighboring pixels and, if time is involved, should have a
persistence effect -- first positive, then negative vaguely like a damped spring
-- which means you could also have numbers less than 0).

As for a primitive... primitive for what?  Do you just want a constant function
representing a specific color?
