This is a simple tutorial on the Rachel Bilson coloring from my upcoming post.
01. duplicate your base and set it to soft light, and sharpen this layer twice
02. make a new curves layer, make a point in the dead center, and slide it to the left until your icon looks nice and bright.
03. add a new layer of #f967ba at 30% opacity (if too pink, change to softlight 30% opacity)
that's it! have fun ;)
