So here's how I did this with photoshop:
Used color select to find all the white and delete it. Set the line layer to multiply to get rid of all the grays.
Used magic wand to select the empty spaces created and created color layers to fill them in, the corners have to be manually touched up to get everything filled in.
Then created color layers of either light blue or light purple set to Color Burn or Linear Burn to make shading layers. Painted with a 50% gray brush in the alpha channel to create shades, touched them up with the smudge tool or an eraser set between 60%-40%. Created hilights painting into a color layer of bright pink or yellow set to linear dodge or color dodge.
Placed a faint pink color layer under some hilights set to multiply to make them pop more.
Erased anything that strayed outside the line art.
