On Windows and Linux platforms, selections are easy to spot as they’re depicted as dotted marquees. This could be another reason why you might not be getting the desired result when using this feature. Because color inversions can be applied to selections, that also means that you won’t be able to invert the colors of the entire image if you have a selection enabled.So if you only want to invert the colors of a specific area of your image, and not the entire image/layer, all you have to do is create a selection around the area using one of the many selection tools in GIMP. Color inversions can be applied locally via selections. If nothing changes on your screen once invert is applied, it’s probably because you have the wrong layer selected. The color inversion will only be applied to the layer you have selected.Here are a few tips and pointers to keep in mind whenever you invert colors in GIMP: 80% gray will become 20% gray, and vice versa. Black pixels become white, white pixels become black, and grays are swapped too. Inverting colors causes them to be swapped out with the colors that oppose them on the RGB color wheel.Īnd the same works for grayscale shades as well. This happens because these are all colors that oppose each other on the color wheel. So for example, red pixels in your image will turn cyan, green pixels will turn magenta, blue pixels will turn yellow, and vice versa. Whenever you invert the colors of an image, you are essentially taking every color in that image and swapping it out with the color that opposes it on the RGB color wheel. The following is an RGB color wheel: Source: Wikimedia Commons Now that you know how to invert the colors of your image, let’s briefly go over exactly what happens when inverting the colors of an image. Here’s how it looks once applied: How the image looks once its colors are inverted. To invert the colors, simply navigate to: For this demonstration I will be using the following example image: For this demonstration I will be applying a color inversion to the example image above.
