I don't understand why.  There's absolutely no relation between
display-graphic-p and the color capabilities of the frame's terminal.
There are graphic terminals that can only display shades of gray, and
there are text terminals that can display hundreds of colors.

There are other predicates and functions to query the terminal about
color support.
