How do I do the colormap 0 palette maker thing you did on g'mic? I can't find where I can enter that line of code.

Nevermind anything else, I can match colors to their closest value in the palette myself. I just need to know how to use the colormap command to single out every unique color together, like that cat image. Thanks for everything else you guys have done, I appreciate your time.

I was being sent multiple solutions, all of which I wasn't sure how to do, so I thought the solution was there, I just didn't know how to use it because nobody was being elaborate enough. I've come across a 4096x4096 image which looked like it included every single color, even the grayscale. I'm trying to make an image like that, only with RGB 64 0 255 to RGB 192 0 255, including all the gray colors. Is there a plugin that does that, basically something that gives you every variation of a color range (R: 64 - 192), along with the whole grayscale version of that color range? If that can be done somehow, I can just use that feature, as well.

Yeah, why? Doesn't gmic have that feature?

I actually already have the palette in the form of a .txt file, because of the "MakePalette" plugin tool, I now just need to use it as a palette for another image. My Ultimate goal is to "purplify" this image.the color palette I'm using actually appears to have only have 1 million unique colors, but I can't use any Paint.NET plugin to basically round up the closest purple to each of the colors you see in that image. I'm trying to convert each color to it's nearest value in those 1 million purples.

Yes

I still don't know how to do either...

I'm trying to succeed at finding all unique colors. and THEN applying it as a palette, to another image.

Sure, expect I feel I wouldn't know how to use that since this is my first time using GIMP.

Where do I input this command?

Wow, that seems very helpful. How would I be able to use that to apply it to an image and use it as its palette?

Converting an image into purple-scale, the palette involves colors from (respectively) RGB 64 0 255, to RGB 192 0 255, and then THAT gradient has a black fade and white fade on it, and then THAT gradient fades into gray by multiplying those colors by 256. I'd send the image here but it exceeds the limit.

I actually managed to save it as a palette using the "MakePalette" tool, and it is a 13830KB .txt file. I just now need to use the SelectivePalette tool to apply it to another image I want to convert, it and so far it seems to really in fact be a matter of time rather than my PC or Paint.NET's program performance.

Trying to use the selective palette plugin tool on an image with 16.74 million pixels, and around 90% of them are unique colors. My PC has a 3060ti and an i9-11900K CPU, and the program stops responding when I use the selective palette tool, but I feel like it'll work if I give it some hours. Is this possible? Is it a matter of time or my PC's ability?

Is there a version of this software (or even a way) to make it fade vertically? I tried angling the object to try and make the fade look diagonal when I angle it back to before, but that cuts out a good majority of the fade.

Let's say, I want to make an american dollar bill look rainbowy. I would take a spectrum rainbow the size of the dollar bill, layer it on top of the bill, and use multiply or overlay, but that changes the saturation and brightness of the colors of the bill instead of directly converting the entire bill's hue into a rainbow. The point is, I only want the hue of every pixel of the bill to change into a rainbow gradient, not the saturation and brightness. How do I do this?
