I made this stripe pattern using the free program Photo Filtre.
It is 2k. You can change the colors of the 4 strips in your favorite photo program by
painting each stripe a different color and repeating the process. 
With Photo Filtre, it takes a couple of minutes to paint the stripes.
Or you can just change the hue in iClone or CC.
The stripes are not perfect, but they look pretty good.
I thank God for helping me. I have no formal training in 3D, just what I have learned in iClone and reading some on opacity maps.
And just watching various Youtube videos and other 3D outlets.
