Short answer: no.
Long answer:
There's a chance one copy = scarlet and two = german pastel.
There's also a chance they're the same gene but it's some other unknown modifiers that dilute them more or less.
There's also a chance they're unrelated.
I will make people who know more than I chime in on the color thread!

Also, a comment
@muddy75 made on Kiki's other thread started me down a color rabbit hole.
I'm not sure how I missed it before but apparently a lot of people think roux dilute and what I've been calling silver pharoah or "tan" silver are the same gene (with different modifiers).
This is making me think back on all of my hatches. I think this gene fooled me into thinking my silvers were producing silver pharoah and confused the heck out of me when it was actually coming from my stock that carries roux.
