More colors?

Hello,


The Nano man page online refers to "set functioncolor" to get the 
exhaustive list of available colors: white, black, blue, green, red, cyan, 
yellow and magenta (+"normal").

On my terminal, the text's color is cyan4. Nano has no problem with that 
because the color is set by URxvt, not by Nano.

When I program, I'd like the comments (starting with "#") to be in a 
slightly different color, such as cyan2, through the syntax coloring 
scheme. It is then that Nano's limitations on colors strike. A 
configuration directive such as
 	color cyan2 "([^\\]|^)#.*"
 	color "#fff" "([^\\]|^)#.*"
produces an error.

Is there a way around this that I did not find?
Or is there a plan to introduce more colors, by name or by hex code?


Kind regards,
Sébastien.
