Just for the record, there are more available options for color than those listed. For example,
crimson,
transparent (<-- transparent, just highlight it and you'll see),
lightblue,
dodgerblue,
cyan,
mediumpurple,
chocolate,
violet,
chartreuse,
magenta,
gold and many other hidden stuff.
We also have the chance to fill in RGB colors, like
#8D2FF6 or
#77ddff, which gives us infinite opportunities for coloring, but it doesn't give us the knowledge of which color has which hexadecimal RGB code. I suggest to link an RGB color code panel that pops up when we click on it, similarly to the [more] button, which pops up the :BIG: elements icons.
I suggest popping up this link, for example:
