A color palette I've used multiple times- features a good range of values that I've used for hair and skin coloring.
I made this palette when I was drawing over the last year and needed a certain range to color pick from. Regardless of what you use it for, it features a good range of vibrant colors that tone from darkest to lightest in the red and blue hues. 

A zoomed in example of how I used it to paint is featured above. ^u^
