Need some help with how to pull off a dynamic light for a specific application

Hi Guys

I have been building a Cinema application in T3D which uses the Awesomium addon.

If you are unsure how this works you can put #webbrowsertexture as a texture name and it updates the textures on a model constantly.

Now when your in a dark cinema you have light that flashes near the screen according to what's being projected.

I want to have a light that changes colour based on whats on the screen but I have no idea how to go about it.

I was thinking of maybe using a cookie from a point light but that uses a image and not the material system.

I wasn't sure if i could use it anyway but when i tried to even apply a cookie to a point and spot light using just an image i didn't get anything which makes me think that cookies don't work?

Does anyone has any idea on how I could go about this? I really thought the cookie idea would of possibly worked but it seem like that doesn't work.

Any ideas from anyone on how to approach this?
