You would need to have a color in the 1st material slot...when you export just a color applied from sketchup, and try to apply the basic material in Lumion, it turns it to white as the color never truly exports. You need to make a color swatch in Photoshop/ gimp or other photo editor and apply it as a texture. After you do that, you will be able to give the color emmitance just like the white as "lights".
On a side note, i have not been using just the sketchup colors, i make a color swatch for every color in my model so i can apply all of the potential options in the material editor. Is the only true way to give reflections etc. to a painted wall or simple color texture.
Hope this helps
