A paint trim can be added to mechs for visual customization. Trims are single colors that can be used on different regions of a mech for decoration. The player can change values for the hue, color saturation, and brightness of the color. Paint trims are applied above paint patterns.
The four checked boxes to the right, when unchecked, will erase the paint patterns from that section of the mech. It is then possible to have a mech completely without markings.
The default paint trim colour is lime green, as depicted in the picture.
