Compositing shadow problem

Update: I am one step further, I think a shadow pass will help retain the object shape in compositing. But as you can see, the front is way too dark and the schadow cast inside is also to dark (not letting a bit of color through. Any tips on how to fix this?

original post:
Hi, in compositing I am trying to change the objects color to a (much) lighter color.
But the problem is, the lighter the color, the less the shape becomes visible.
Looks like the shadow also becomes lighter with the color change. And this results in a poor defined object shape.

It seems that the object fades away as a result of the lighter color. This way the shape of object is less visible.
Is there a fix to hold the shape definition?

shape less visible in lighter color

shape better visible in darker color

Try changing the opacity of the shadow catcher.

Your chain looks a bit unorthodox to me.

  • I don’t understand why you’re mixing a color balance node, instead of keeping the color balance in series.
  • Also don’t see why you’re mixing all of that with the original.
  • You’d have more control of the diffuse falloff color if you also use an AO and/or shadow pass

Need to rebuild the beauty pass and make adjustments in the proper pass. In this case will be the diffuse color using cryptomatte alpha as fac input at the color balance node, or any kind of color node.

thanks, I will try this

Yes, I understand now the basic setup of dir+ind then multiply by color. But for shadows and AO I did not find a general idea how to hook these up, so I was just trying with multiply.
