I want to change the color of an object which has different shades of green into different colors and specifying hex as target colors. I want to change the object from green to any hex color I specify and supporting the shades of the green. I know I can switch colors using Rotate Colors feature of GIMP. Though I am limited by the colors on the wheel. I also explored the Exchange Colors option but changing the r/g/b thresholds causes other non-green colors to change. I only want to change the green color and nothing else. Is there an option to do what I want in GIMP?

Thanks.

You can also use the Channel mixer to make an image that represents your wanted selection (likely positive green, negative /red/blue), and then use that image as a selection (in the Channels list, right-click any of the R/G/B and Channel to Selection)

I combine the image from lutCreator.js with one still of the video (with the green screen) in GIMP then apply the filters I want. I have managed to change the green screen color into any of the color ranges available with rotate colors and create LUTs that work with those. Though, I want a specific hex color which I cannot reach in ...

  • In the color selector you can always enter the hex code directly?
