Change Colour without Changing Value - mymaloneyman - 12-14-2019 Hi there, I'm using GIMP for graphics for a video game project, and I'm trying to make several different colour palette variations on the following palette in such a way that the colour changes without the alpha values changing. Basically, after colourizing, converting the palette to greyscale would result in the exact same greys. How could I accomplish this? Here's the palette in Hex: #111111 #818281 #a9aaa9 #d4d5d4 RE: Change Colour without Changing Value - Ofnuts - 12-14-2019 There are may ways to convert to grayscale. Color->Desaturate has five opfions! The Gimp color selector can work wit three "color models", RGB, HSV, and LCh. With LChi if you don't change the L value, the resulting luminosity shouldn't change, LCh can be tricjy to work with (you can have out-of-gamut color (the purple ranges). In HSV, the "V" is a less accurate approximation of the perceveid luminosity, but is much easier to work with. |
