LED screens

Hi! i’m doing a festival stage and I need LED screens to be more realistics, and I’ve tried in so many ways but nothing that is satisfying. as you can see, the screens are white, but around the light is blue. when I put an image with blue color, and put blue stuff in each and every setting of the emissive material, it doesn’t come out as blue as a real LED screen would.
The thing is that I need that glare effect, so I need to put the strong light, but as i put it strong the surface becomes white.
I need the same effect that you get with “lens effect” in vray.

can anybody help me?
or will it be a feature that will be improved in the years to come?

Hi, I’ll show you how to give color to the light with an example:

First the moon was white as always in this image posted in the gallery by me

Then I’ll show you with an image how I changed it

the final render result is at 2k

Maybe try giving your screen a video material and then changing its emissive color.
