Dyes? Why can't we get a color wheel?

[Ranaku]

Why are we extremely limited to a few dye colors when we could have a decently-sized color wheel? I think it'd give the glamour system a HUGE improvement, and glamour is something all people do, to a small or bigger extent.
They could do it like, if you want x color range, you have to buy x dye. And that would keep the dye system the same. Suggestions on this are welcomed.

Because dyes are literally the best selling thing on the mogstore. Can't give people the real black or white for free.

And a wheel would be a step in that direction. Some they won't take for sure.
