Set colors to folders

[giudansky]

Pleeeese do you think it could be possible to custom colorize folder rows ?
Yeees I know I can do it by timestamp and type but I really need a quick way to colorize some folders on the fly, not by any specific attribute.
Would this feature be possible, ever ?

Thanks

How many folders should have their own color? Is it, for example, 200, 2000, 20000?
