Merge coloured srfs


I have been playing around with Lunchbox’s new isovist tools. I have it working almost as intended but can’t get the visibility correct.

Basically I have two isovists with different colours. I want to ‘superimpose’ the two analyses similar to the diagram below. I’m not sure the best way to approach this in Dynamo. Should I play with transparency (alpha channel) or generate a new colour. Is it possible to do boolean unions with colour?
