How can I use ECOTECT RGB as a driver for Galapagos?

Hello guys,

I am trying to optimize my form agaisnt the sun by using ecotect mesh data and linking it to galapagos. 

I have the Ecotect part up and running but I can not find a way to send the rgb values to Galapagos... 

Is there a way I can extract the RGB values specially R as a number to find an optimized form? 

Please let me know.
