Devmode JSON for wheels (although really, it's only different from the one loaded in that it's always on, and the color is FFFFFF instead of 999999)

Ingame appearance after devmode


Here's the color set to FFFF00 as well, so I think maybe the blue is being dropped along the way

Turns out I wasn't dropping the blue. I was just dividing it by 255 due to some old logic. So basically all your particles would be permanently on f.lux settings.
