Thanks, @NathanBaulch for your time to contribute to this change, it was a long time due. 🎉 🍰

I was thinking if we could also add flags for this color support in CLI utility it would be really great addon!

Good idea, I went with -l since all the other letters in "color" are taken.

Hey @NathanBaulch, could you please review the changes once, then I'll merge these changes

FWIW, the color names I went with are the standard SVG/CSS ones, as listed here: https://www.w3.org/TR/SVG11/types.html#ColorKeywords
In case you wanted a more "official" list rather than pointing people to color.go here.
