It can by any kind of primary color, red, blue, green, purple, any color you like.
It can be styled anyway you like but (it's) not meant to be styled to look good. You can wear it very free and it looks great.
We like to apply the color for (a) bold look, so we do a lot more thicker or wider highlight than a very fine highlight.
It's just the work of the shape and detail of how we finish it and it should work for every type of face.
