Good point, @jakub-g , I agree with you.

I would say that maybe it will not be used in many production environment, but it could even be (from black to white, for example, or for smaller, not strongly styled sections, and other different use cases), and it is costless for us (already implemented).

I would hold the 17 standard colors are: aqua, black, blue, fuchsia, gray, green, lime, maroon, navy, olive, orange, purple, red, silver, teal, white, and yellow.
