Ladybug radiation mesh >> perforations from color data

Hey GH world! I'm new and struggling to piece together this script. Trying to use a Ladybug radiation analysis mesh to inform the size of openings on a facade system. I found on part of another discussion the best way to do this deconstruct the mesh by it's colors derrived from the analysis to get a new set of points, but I can't get it to work out. Following that I'm hoping to apply a voided shape to the point data that varies in size- where the most sun exposure has the most dense perforations, and the areas receiving the least amount of sunlight have the largest openings.

Any help at all would be GREATLY appreciated!!!

The script attached uses the 2017 Ladybug update, so EPW link is included
