Artist Uses AI To Extract Color Palettes From Text Descriptions (arstechnica.com) 18
A London-based artist named Matt DesLauriers has developed a tool to generate color palettes from any text prompt, allowing someone to type in "beautiful sunset" and get a series of colors that matches a typical sunset scene, for example. ArsTechnica: Or you could get more abstract, finding colors that match "a sad and rainy Tuesday." To achieve the effect, DesLauriers uses Stable Diffusion, an open source image synthesis model, to generate an image that matches the text prompt. Next, a JavaScript GIF encoder named gifenc extracts the palette information by analyzing the image and quantizing the colors down to a certain set.
DesLauriers has posted his code on GitHub; it requires a local Stable Diffusion installation and Node.JS. It's a bleeding-edge prototype at the moment that requires some technical skill to set up, but it's also a noteworthy example of the unexpected graphical innovations that can come from open source releases of powerful image synthesis models. Stable Diffusion, which went open source on August 22, generates images from a neural network that has been trained on tens of millions of images pulled from the Internet. Its ability to draw from a wide range of visual influences translates well to extracting color palette information. Other palette examples DesLauriers provided include "Tokyo neon," which suggests colors from a vibrant Japanese cityscape, "living coral," which echoes a coral reef with deep pinks and blues, and "green garden, blue sky," which suggests a saturated pastoral scene. In a tweet earlier today, DesLauriers demonstrated how different quantization methods (reducing the vast number of colors in an image down to just a handful that represent the image) could produce different color palettes.

I'm not going to mod you down, I understand your opinion and where it comes from, but I would disagree. I expect a lot of artists. both fine art and graphic professionals, would hear this news and say "I'm not sure HOW that will be useful, but I bet some people will do some cool stuff with that".
Sure, using the entire Stable Diffusion data set for such a limited tool is technically overkill, but it's very interesting that it can do this so (relatively) easily, and does make me think about the possibilities

What about generating a 64x64 image, or even smaller? That would take basically zero time.

There are no "images" being copied with SD. The amount that SD knows about the average image in its training dataset is less than 1 byte each.

Yeah, it's absolutely ridiculous. There are much better ways to achieve the same end.
I don't even think you need the image generation step, or image search in its place. There are a ton of named colors and palettes around already, which are probably closer to what you'd expect than whatever you'd get from some random image. A simple search matching search words to named colors, averaging similar colors until you get down to the number of colors you want, would probably work just fine.

This seems like the logical way to splice two existing processes (AI image generation and palette extraction) together. But for any useful purpose, wouldn't I want an additional step of interactivity when picking the image result from AI generation?
