The c olour of this directional light you are considering is as seen in the video adnd thumbnail on this page. Derivible, texture you own.

Up until now the Spot Lights on IMVU have all been fakes, with cones giving the effect of light coming from them, but now we can actually have directional lights such as spot lights which we can move to light up certain areas of a room or scene. Add more that one colour to each corner of a room for example, Tip slightly angle them differently to see the effect of the different colours. Only works in rooms that have Ambient Light.
