The colour preset for orange (e), doesn't even look orange. It's just another shade of yellow (maybe I'm colour blind). If possible, I would like to request the orange colour preset to be updated with a more vibrant orange... Something like the Grub's colour as shown in the screenshot
The left character has all of his limbs set to the colour pattern of orange (e).
Or we can take it one step further and set hex colour values and alpha transparency for each limb! But... That's probably too complicated, so let's just stick with the first option.
