From a client email:
My question is what Jon Renau wig color is closest to Gabor's Chocolate Caramel?
None of the JR colors are an exact match to the GL27/29 (Chocolate Caramel). The closest approximations are 27MB, 27MBF, and 27T33B. These colors can be kind of hard to find in their newer styles. When all else fails, FS27 will also work well, but it is substantially lighter due to the light strawberry highlight colors.
The issue here is that #29 in the Gabor color. It's got just a hint of brown blended in, and that is something all the colors in the JR line lack. ;)
