The blue was mixed up from white and medium blue. I wish I could remember the ratio. I have the McCoy too, and I sprayed the shirt for that one at the same time.
The eyebrow ridge is part of the sculpting. And in truth, most people have a ridge area where their eyebrows are. The eyebrow itself is usually contained withing this ridge.
