I thought I'd show a side-by-side comparison of all 6 skin tones for anyone interested. I used female shura as my model, and only grabbed screenshots of the avatar this time. Note that this is just a general look at how the different skin tones will look on your avatar, and it may be slightly different depending on your chosen race. Expect sylphs to be much more pale than the other races.

I may eventually do a hair dye one (once OB starts and there's an item mall) depending on how expensive the hair dyes are.
