: How to change ( invert ) color on a high quality photo of a product? There is a black leather with a yellow thread and my client wants me to change it to a medium gray leather with black

@Hamm6457569

There are many ways to do just about anything in Photoshop. Two approaches that I would try would be:


Duplicate the original, convert to CMYK and apply the yellow channel to the black channel in Multiply mode (Image > Apply Image). You could also try simply copying the yellow channel and pasting it on a new layer, using Darken or Darker Color as a blend mode.
Isolate the yellow thread with Select > Color Range, then remove the color with Hue/Saturation (fine tune the mask by hand). Darken the thread with the Burn tool or a black brush in Overlay mode. Keep the opacity low (30% or less) so you can build the effect gradiently. The tricky part is maintaining the texture, but that's going to be a matter of careful brush work and close observation while you're working.


There are probably several more that I'm not thinking of right at the moment. If I saw your original, I might be able to give you better direction.

I'd probably just use the magic wand, experimenting with settings of how many pixels it is tolerant of to select those areas while holding shift to get multiple selections. Then once all is selected experiment with curves, levels or brightness to get the look you want.
