Keeping Steel Gray horses gray?

What do you do to keep your nice dark grays, well... gray. I know some stay darker for longer than others, but there should be ways to keep them dark even if they are lightening up quicker, right? Tell me what you do. Thanks in advance! :)

There is absolutely no way to halt or slow the progression of the greying process. It all relies on genetics.

Exactly. Much as I hate to say it, there's nothing to be done. I love those dark grays and I'm not a big fan of white grays but there's just no way to change how the gray gene changes them.
