I, uh, wound up deciding I should do another colorized NP dealie.
Obviously. (Cough)
ANYWAY, my main goal on the left version was a background that worked for the rental shop without clashing with the uniforms or foreground characters. I settled on a lower saturation blue of a slightly different hue for the background to give the impression of it going with the uniforms without blending too much with them.
The second version is my experimenting with using existing palettes in different situations, and seeing how they'd look with the background colors I chose. Tensaided's been given Nanase Craft's palette, and all but Susan's skin uses colors from Plant Grace's color palette from the previous sketchbook.
