Defining Color for Point Lights in Thea for SketchUp
Point Lights parameters in Thea for SketchUp can be modified from the Lights tab in the Thea Tools window.
By default the light color is White. To use an RGB value, you have to apply a color to the light component using the Bucket Tool.
In this way, all instanced Thea Lights can share the same parameteres (intensity, falloff, etc) but each one can use a different RGB color.
