If the current gradient is grayscale (or even pure black and white), you get the grayscale image - again with a different way to control the outcome Colors->Map->Gradient maps an image to the active gradient.Separate each of the color channels on the image - with an optional interpretation of the color image as "CMYK" or "HSL" besides "RGB" into a separate, grayscale, image (or layer). If you check the "monochrome" box, the target image is grayscale - this allows a lot of control on the resulting image allow you to compose channel values on the resulting from a percentage of each component on the source image. This is GIMP 2.8 - Unstable GIMP 2.9 has even more algorithms to desaturate. Colors->Desaturate which offers 3 different algorithms to generate a gray value from given colors (the options above allow a lot of control on the grey levels, since you can slide the Luminosity control as well.Colors->colorize.and again, pull the `Saturation control to the leftmost position.

and pull the Saturation control full to the left To simply reduce saturation of the current layer to gray levels, and continue editing the image in the RGB color space, there are several options: To do that, go to Image->Mode->Grayscale - just as suggested on the other answer. There are several ways of doing it in GIMP, and it depends on the end-result you want.įrom your question, one can't know if your desired result is really a "black and white" (only) image, or a desaturated image, with up to 256 shades of gray.Īlso, you have options to either desaturate only the active layer or selected region, and continue editing the image in the RGB color model, or convert the image grayscale colorspace - which will convert all layers, regardless of selection, and automatically cast any colors to gray on painting.
