How to compare selective color edits in Split on Mac
Sample a color from your photo, keep it vivid against monochrome, then use Split to compare the original and edited image.
- What you'll achieve
- You will have a selective-color edit with the chosen accent preserved and a Split view that shows the original above the edited result.
- What you need
- A photo you want to edit in Selective Color Photo FX.

Selective Color Photo FX lets you keep a chosen color family visible while the rest of the photo turns monochrome. This guide uses the app's Split comparison so you can inspect the original and result together before you finish.
