Stefan,
I almost choked on my morning coffee when I read your last request; a recipe for PC10!?!!?!

We have 1,744 members here and I'll bet if you actually canvassed all of them we'd have over 100 absolutely correct versions of the elusive shade to choose from.

I really like Tony's suggested method; makes as much sense or more then any I've seen prior, and actually I kind of like the colour he's come up with!
Enjoy your DH2 and I'm looking forward to following it; it's getting closer to the front of the line in my project schedule as well. In the interim think of PC 10 like snow flakes; they all look the same but actually of the billions out there no two are alike. To Quote Keith (Kornbeef) "that's half the fun of it"

Cheers,
Lance
PS. On a serious note, search PC10 here. There's been some really good formulas given here, just a matter of which YOU prefer!
