We could test if the variable is set first (test -n "${foo+set}"), at
the cost of a bit more complexity.

I also don't like the duplicate list of color types, and I considered
doing something similar to what you suggested, but I decided against it.
I'm a bit worried about bizarre syntax errors or code execution if
say_color() is used improperly. ('eval' with uncontrolled variables
makes me nervous.)
