Change Shadow Colour?

Is it possible to change the shadow colour?
I'm making a blueprint style, and I'd like some soft shadow indication, but I 'd like to be able to control it's colour. I'd like to set it to white instead of black.Am I missing some settings here, or it it simply not possible except doing it in post?

Thomas, you can get a white shadow if you set the background color to black and the Dark shadow slider all the way to the right. If you made your blue background a watermark image, you could have the background and shadows set as above and I think you'd get a white shadow on a blue background.
I haven't done exactly that but for some styles I do change the background color behind the watermak underlay to change the color of the shadow.
Edited to add: I didn't have a blue background to use as a watermark but here's that MDF watermark from the Assorted Styles library mixed with the black background/white shadow thing. In this case, I did have to edit the line color back to black. It normally reverses when the background is changed to black.

Ah, yea. SU automatically changing colours like that have annoyed me. Maybe it has some purpose now.
Still, it'd be nice to be able to control the shadow better. One for the Wishlist. It's be nice if you could specify in styles a hatch pattern, so you could get white diagonal lines as the shadow fill.... hmm....
-
So is there any way with Ruby to figure out where the shadow edges would be, create faces and fill them with a hatch pattern? Of course the script would have to be able to update for time/date/latitude changes in the Shadow Settings.

Hi Guys
I know Al from IRender has had program in development for some time NprTools that has sketchy shadows, but has not been released yet. Looks like what your taking about.

ooooh!
that's exactly what I'm after! -
I was wondering if anything came of this question? I am also looking for a way to change the color of the shadows in sketchup. when we used to hand render everything we would never use a black shadow ...blue violet or indigo always brought more life to the drawing for those of you who remember prisma colors.
thanks,
Chad

There isn't any native way to change shadow colors. TIG did a plugin called Shadow Projector which works on faces to project an outline of the shadows, you could then create faces and apply materials or colors to those faces.
For my use I find it's just easier to export a shadows-only image from SU and manipulate it in an image editor before combining it with another image export. With that method it's also possible to give the impression of multiple light sources as in this image.
-
Here's another example in which I used multiple image exports including a shadows-only image. The shadows were treated with a sketchy pencil effect and the colored faces were treated with a watercolor effect in Fotosketcher. They were then combined with a lines only export using one of my pencil lines styles. Quick and easy.

I always just exported my shadows by themselves and changed the color in PS and multiplied them on.

Exactly what I do.
