Powder Coat Color?

[jy211]

tow truck is on the way to pick up my 55' chevy frame to take to the sand blasters. From there onto the powder coating place..
Here's my question...what color should I powder coat my frame?

My tubular control arms will come glass black, as well as my new moser rear end.

My Hellwig sway bars came in and they have a rough charcoalish color to them....

I am probably (as of today) going to paint the car charcoal grey (off the lexus RX350)(or a gun metal) and white (not sure if I will do a standard white or metallic)...in a traditional 2 tone style....

Any suggestions as far as what color to powder coat the frame???
