Thanks for the image. It's very small, do you have a larger version? I also would like to see your attempt at turning the cabinets white.
Sometimes the exact color of the swatch will not translate and will need to be adjusted. We can look at using the Eyedropper Tool and the info panel to adjust colors. But let's address the changing of the cabinets doors to white first.
Unfortunately I only have small, low quality photos to work with at the moment. Going to be going there this weekend. All previous owner's furniture will be gone and will take better photos which will help greatly with this effort. Working with what I have now in an attempt to get the process figured out so that I can hit the ground running once I have the better quality photos. I have attached the actual photo file, not sure if that will help provide better resolution/size or not. Also attached is my attempt at making white one section of cabinets via layer mask>decolorize>adjust levels. I also have a hue/saturation layer (not visible in screen shot) but it does not seem to be an ideal way to make them white.
Ultimately my goal here is to be able to make layers for both walls and cabinets so that I can test different color combinations on both. Have Paint Manufacturer color swatches downloaded to PS and want to be able to test real paint colors to find optimal finished product. Leaning towards making cabinets white or slightly off white and painting walls more of a gray. Other option is for possibly white-ish walls with grayish-green cabinets.
One challenge with cabinets is the wood grain. Every method I have tried still shows wood grain. In real life, after painting (with whatever color) wood grain will be invisible. I had tried using a solid color layer mask, but you lose the definition of the cabinets (result: one big solid white shape). The wood grain isn't a huge deal, could look past that, but thought I would throw that out here as another challenge I am facing.
Again, your help is much appreciated!
