Base CC5 character creating using the CC5 freestyle viewport morphs and then fine tuned using the headshot 2 and CC5 morph sliders. Clothing and hair are from the marketplace. Female Black Outfit from Polygonal Minatures and the hair is a combo of side swept and side clipped hair from Hair Builder Edgy Hair 3 bundle from Reallusion. Dual hair colour created adjusting the root and end colours as usual, but to get the end colour to extend closer to the roots the way I wanted, I had to modify the root map in photoshop. I couldn’t find a way to do it in CC5 and get the result I wanted.
Here’s the recommended workflow for making your adjustments.

CC5 uses the same texture-editing method as previous versions of CC, and you can also refer to the other adjustment options available for Smart Hair.
Hope this helps!
