When I logged on my Mechanic, they gave a lightbulb quest with the Bear instructor telling you about it, and he says to pick one of the three colors.
I picked one and got Blue for free. Didn't everyone just get the color that they wanted to when they picked it?
I didn't have to use the palette swapper thing at all, but he gave me one, and one on my Battle Mage too.
But I did hear that the palette was glitched and the color change was only viewable to other people and not yourself.
To activate it:
-Accept the quest lightlbulb on the side with Checky, giving you the options of red, blue, torquiose,and normal. (only can choose once)
To change colors after:
-Log in and recieve an event quest which gives you an sp reset sroll and a microchip. Use the microchip to change into a random color (unlocks the colors green, purple, pink, and yellow)
-Log in with another resistance charcater (BaM or WH) to gain the same event to gain the sp reset scroll and the microchip (the microchip is tradeable)
-Buy more chips from other people willing to sell it
-Buy more chips from Checky at 1m each
-Keep using until you are satified with the color
