Attribute a material to grasshopper color

i have a group of meshs with color given to it from the 'GECO' plug in which collected the ecotect solar radiance. I basically want to use like 3-5 different types of colors based on the amount of sun on each panel. so i have the different color panels where yellow gets more sun and blue gets less sun. so i want to basically have a panel thats clear, one thats opaque white and 2 or 3 in between. here is an image of my mesh group:

so how do i go from this, a collection of different panels with different colors, to narrowing it down to only 5 colors and attributing those colors to a corresponding vray material?

thanks a bunch,

just bake the objects(per face) with giulio piacentinos bake c# component and assign the color as material and it will render fine in vray for rhino.

If you want to use a other software use fbx as export

cheers,

i gave it a try, combining the two files, but i get an error at the end that says 'no data was collected' any ideas or is there a glitch in the file somewhere that i made?
