Oh, the Light and Motion lighting concept with a blue filter on the light and the red filter always on is when you are shooting macro up close, the blue light and the red filter balance out for proper color rendition, objects in the background that are not illuminated appear with more red added.

Their whole idea is when you shoot a clip with subjects both up close and illuminated and far away and not illuminated, the colors will be more evened out, instead of the traditional up close with lights on, good color of stuff up close, but subjects far away ALSO in the clip will be their usual all blue.
