I am...ah, attempting, to create a personal book cover as a bit of inspiration to finish the title. It was going rather well until I tried to adjust the color on the bone to that of the woman. I just can't seem to get it right. Sometimes I look at it and it seems too blue, so I tried to make it more green, but then it just looked grey. If anybody could help me with this, I would really appreciate it. 

If the image is too difficult to work with by itself, PM me your e-mail and I will send you the .PSD file with the layers. Thank you to anyone who wants to give it a whirl!

Halp. The colors don't match!
