Bike Color Customization

I’d like to suggest a bit more ability to customize the colors on bikes.  Perhaps the ability to enter numeric RGB values and/or desaturate the colors.  A lot of us try to match our existing bikes, and quite often it’s impossible to come even vaguely close to the right colors.  Many really common colors are difficult to pull off on some bikes.

Also, on the steel bike, it’d be nice if the colors remained either “gum” brown or were something neutral like white or black.  The weird purple and teal hoods that you end up with if you change the color of the bike from the default don’t look right.

In game I drive on Trek Emonda, but its impossible to change this bike color. On other bikes its possible to change color, but Trek Emonda bike color change is impossible, why? How to change that bike color???
