I think this is a wonderful idea. It would encourage players to make unique records (like FL+ HR). It would also help differentiate scoreboard plays: for example, HD+HR and HD plays are very different yet they possess the same S color. Likewise, DT+HD and FL+HD are very different yet have the same color.
Because of the reason stated above, I don't think the colors should be based on mod score multipliers.
Instead, as people stated before, it could be as simple as having HD be light blue, FL be darker blue, HR be orange and DT be red. The combination of those mods would simply yield the combination of those colors; for example, HR + HD would yield light pink (I think). Easy mod would yield a special Green S.
Also, skinning needs to be accounted for.
