When using the manual settings, the two different HUDs have different codes.
Omni Hud v5 :
R = Red
Y = Yellow
G = Grey (light or dark)
Alternative Skins Huds ( free in the mainstore near the demos) :
SR = Saturated Red
SY = Saturated Yellow
DSR = Desaturated Red
DSY = Desaturated Yellow
When you need to tint the feet/hands, just copy and paste the /13 skin R,G,B code into chat in world, and your hands or feet will change colour.
Then use the same numbers to tint the blender layer when wearing the number that matches the code supplied.
example: hands DSR 12 /13 skin 154,124,132 wear blender DSR 12 and tint it with 154,124,132 in the RGB panels in edit mode see our tutorial for help.
Important If you are wearing feet and hands at the same time, and the tint is different for either one, remove the ones that dont need tinting before you put into chat, as it will tint everything at once.
Hands – DSY8 /13 skin 239,229,227
Feet – DSY12
