Just started playing around with the generator when I noticed I couldn't make red haired characters, only pink. Dug around quickly and found Program Files (x86)\KADOKAWA\RPGMV\Generator\gradients.png While you can't seem to add new color gradients you can do replacements. Takes a few seconds using gimp to change a color. Simply select a gradient you want to replace, cut it away leaving a solid line. Then select you light color you want for foreground, and black for background. Pull gradient tool across selected line horizontally and you have a new hair color choice. http://imgur.com/a/7ywDE Note: The hair colors share gradients with eyebrows, beast ears, and tail.
