I have AllenM do my cerakote work. He has a ring of color samples so you can actually see what the color will turn out like. I had a Savage bolt gun rebarreled into a .458 SOCOM and it was coated in Sniper Gray and I absolutely was amazed with the color once it was applied. Any shop doing cerakote work should have the color samples so you can compare them and actually see the finished color. There are several people doing the work that "blend" colors to get what they want which is great as long as the customer knows if there is an issue and a repair is needed, the color might not match.
