I’m trying to use the IMAGE SAMPLER component to get a simple color mosaic effect, but there are too much kind of colors by the default setting, may I have just 12 colors on my surface?
I knew that we could reduce it by colour brightness. but I have no idea to reduce RGB color.
I have worked on some projects that had to deal with a mosaic-like effect
if you have to reproduce an image using a limited number of colors, and the image must be still “readable” after the process, I really suggest to downsample it in some “dedicated software” or through code, and then sample it in GH when the colors have already been translated into the final limited color range
color dithering, noise and other “special treatments” you can use while downsampling will get a more vibrant result
