This happens to me all the time.
I'm starting out an image, and for the life of me, I just cannot determine what color I should use for the skintone. I wish I had a crystal ball that would show me thirty minutes into the future so I can see just how a character will look after applying all the necessary shading, anatomical detailing, and highlights based upon the base color I use. A lot of times, it'll appear too faint, too desaturated, or on the flip side, way too bold and gleaming like a bronzed deity caked in a thick lathering of walrus grease.
Which is delicious, by the way.
FORTUNATELY! The folks at The Humanae Tumblr
seemed to have a crystal ball of their own. Not so much one that shows the final product of my work, but one that certainly told them of my many incredibly frustrating endeavors into spending a good chunk of time shading a character's skin only to realize the base tone was absolute garbage.
Then again, they wouldn't really need a crystal ball for that. For all I know, they could just be my neighbors three addresses down, and judging by all the noise complaints, they'd certainly have their own brand of clairvoyance as to what really chaps my armpits. But whatever, whether it be omniscient psychics from Mars, or terrified residents laboring feverishly to keep the Dave beast docile, take a moment to thank the magnificent descendants of Valhalla who slapped together The Humanae Tumblr
Happy coloring, folks!
