Paint colors allow you to determine which materials represent the Primary color, Secondary color, Wheel color, Interior Trim color, and Dashboard color. To select the paint color for a material, navigate to Material Properties > Sollumz > Fragment.
By default it will be "Not Paintable", meaning the shader will not be affected by any paint color.
Not all shaders are paintable. If you are trying to set up a paintable vehicle material and you are getting the "Not a paint shader" message, then you need to use a different shader. Typically you'd want to use a vehicle_paint shader for the body of a vehicle.
