15K Color Slider!!! Arrurate color Dye System!
Akilles
OHHH, How about like a 15k Dye trader! get this! it opens a window like when u hit the "H" key except it is a bigger pic of hero w/o cape that you may spin around! Under it you have a box with a range of colors like your color palette in photoshop underit are sliders in 3 sliders in RGB fromat and below that slider for the value (light to dark) we can make crazy colors for that fun armor and not have to guess as we can view the color change in real-time as we adjust the sliders the costume adjusts. when you are satisfied you can pay to have the dyes crafted and BAM! your all done. Maybe even specify which item you wish to customize the dye. The ability to control a gradient as well would rock. It would help that 15k set you slaved for become that much more custom and seperate you from the masses who have the 15k set.

Or have it like the guild emblemer and shade your armour to your liking instead of guessing, then charge a reasonable price.

5k a piece sounds reasonable to me

Except then everyone would just take whatever color and make it very, very dark, so it looked black.
