I have an image on a single layer with various colours and I have several separate Hue/Saturation layers with layer masks based on those colours in the image. So for example, charcoal linked to a Hue/Saturation layer above it, targeted by a layer mask, then grey with a similar Hue/Saturation adjustment layer above it and light grey with the same.
This means the charcoal will have one Hue/Saturation alteration, while the grey and light grey will each have completely different Hue/Saturation alterations with their own adjustment layer.
This works fine, but if I change any of the colours in the image, the corresponding colour-range-matched Hue/Saturation layer will not update itself to match.
I’m guessing this can’t be done. Targeting the colours in the image with a colour range on the Hue/Saturation layer won’t work either since the image is greyscale. I need this to work with many different (but similar) images.
I tried using an action even though it’s not ideal, but it didn’t work at all since the colour range selected was fixed – I guess; it isn’t actually doing a colour range based on the colours of the image being used. Very odd.
