Changing color in Photoshop

[glorybound]

What am I missing?

I don't remember this being a problem. The owner wants to replace colors, but I am getting nowhere.

Keep in mind, I am using GPU, so no raw elements.

I think the cabinetry is just too grey in your starting image so when you multiply the paint color times this you just a get a darker version of the paint color, not the intended paint color. I think you can somewhat account for this by making a layer above the paint color that is the "Gray" of the cabinets and setting it to "Divide". This will lighten up your paint color to account for the grayness of the cabinets. I think this should all be done in 32bit mode if possible to maintain highlights.

I don't think doing this job without raw elements is particularly wise. GPU seriously doesn't let you render raw light, raw gi and raw diffuse passes?

[glorybound]

CPU doesn't directly, but I think you can combine several passes to make a raw pass.

I think I have to render these out using CPU. I have this from an earlier post and I'll give it a try. The problem is, there are 100s of them.

Okay, I have it working. Thank you, guys!

So what did you end up doing?

[glorybound]

Followed Neil's post. I used the six elements and stacked them properly in Photoshop. I had to switch to CPU, however, I think with some more work I could do it in GPU.

Nice! glad to see you got it up and running. I'm surprised that GPU still has that limitation.

[glorybound]

Someone posted the steps to create RAW elements using GPU. Each RAW element consists of three other elements, so it gets complicated.

[glorybound]

VRayRawGlobalIllumination = VRayGlobalIllumination / VRayDiffuseFilter
VRayRawLighting = VRayLighting / VRayDiffuseFilter
VRayRawReflection = VRayReflection / VRayReflectionFilter
VRayRawRefraction = VRayRefraction / VRayRefractionFilter

in most cases you can simplify the setup by doing color adjustments on TotalLighting element (Lighting +GI on gpu):

Using the Multiply mode only areas being perfectly white will end up matching your target color exactly. Anything darker will be a darker shade. So you would need to use for example a Levels adjustment to brighten up the source area before multiplying it with your target color.

Here is a workflow that is more artistic (WYSIWYG) and requires fewer layers, should work for you:
For the example shown in the video a Gradient Map (Adjustment layer) would work. You set the color of the gradient to your target color (e.g. from blue (left) to black (right)). By moving the left color stop of the gradient you can decide exactly which brightness level will map to your target color. What is even better is that you can also exactly decide which color the dark tones will end up by changing the right color stop of the gradient to something else then black.
