Hello does anyone know which plugins and effects I need to use in order to acheive this type of background effect shown in this video? I want the slightly purple effect without my lightbulb looking too bright and I am thinking defocus to get that little bit of blurred background effect does that make sense?

here is what i want my background to look like:

Here is what my video background currently looks like(The defocus is only applied to the left lamp area and the rest of the video is just normal without plugins):

Thanks,
