Color sharps and flats a different color

Hi, my wish is to get a plugin like "colorhalfsteps" but that gives the choice of the color, and most of all, the possibility to color sharps : "army brownish green", and flats : "orange".
On the frequency scale , I color staves lines in Blue, Green, Yellowish and Red to match the high pitch of Sopranos, then Altos, Tenors and finally the lower frequency, red for Bass.

With the same spirit, the color for sharps has to be a higher frequency than for flats.

Actually, I use #D46503 for flats, and #666F16 for sharps. Those colors are easy to read on a screen, and are enough light when we print a score, knowing that many printer will darken a bit all they print.

But doing it by hand is tedious.

This ends my wish list ;-)

I'm no programmer, but my guess is that it is doable by the ones who know...

Thanks in advance
