Bootstrap tests on Color Tool

Per #1052, apparently there's no tests already in place for color tool.

This represents going from 0 tests to at least some base level of testing infrastructure so people can't use the "there's no framework, I can't write a test" excuse.

I'd imagine we should have a ut_colortool for checking some of the methods that builds in the classes/componentry and then an ft_colortool that attaches to the console and attempts to run some of the commands and see what it does.
