Using coloured sky description with genskyvec?

Hi Greg,
is there any option to use a user defined color description rather than the inbuilt/uniform color description (-c) in genskyvec?
I’m working on a colored sky model for gendaylit and using colorfunc for the sky description and want to compare the data for the tregenza patches with measured data. I thought to use this handy tool instead of sending rays manually, but it seems the color information is “fixed” in it.

cheers

sorry - I posted it too early. It works also with colorfunc… needs just the -c 1 1 1 option.
cheers
