In Mathematica notebook interface, you can evaluate:
and you get a colored squared representing the color. Then I can copy and paste this color square and use it as input, like so:
which I find very readable. However I would like to be able to enter the blue square directly, instead of having to enter and evaluate
Blue in a separate cell to get to the square.
Is there a key combination (similar to the usual
Esc + a + Esc to get greek letters) to get the color boxes?
