a "nice to have" for me would be an additional int32 variable as colorpalette info in the struct b2Color.
I'm using this actually for gif rendering with libgd.

I don't quite understand. The colors are specified by Box2D and passed to the debug drawer as const references. How would Box2D know about your color pallette? Can you convert the 3 floats into a color pallette entry?

Yes, I actually do

Code:

void GIFDraw::SetColorPalette(gdImagePtr im, b2Color* c)
{
    c->color = gdImageColorAllocate(im, int32(255.f * c->r),                                                     int32(255.f * c->g) , int32(255.f * c->b) );
}

before starting physics engine and gif rendering.
So i have the same variable (b2Color) as DebugDraw to pass to the GIF drawing functions.
But its only nth, for comfort, not really important.
