[Radiance-general] Colouring shadows

[Nick Devlin]

Dear All, 

I am trying to complete some overshadowing comparisons between an existing
and proposed buildings. I would like to generate a single set of time based
images to show the extent of any additional shading from the proposed
compared to the existing situation. 

I would like to be able to highlight the shadows from each building in a
different colour. I could run the simulations twice, for each building with
a bias on the rgb of the sun and combine the images, but I am not sure
whether this would work. 

Can anyone provide me with some guidance.

Many thanks

Nickd
