That whole bit about color blending and transparency and LLMs "not knowing colors" is hard to believe. I am literally using LLMs every day to write image-processing and computer vision code using OpenCV. It seamlessly reasons across a range of concepts like color spaces, resolution, compression artifacts, filtering, segmentation and human perception. I mean, removing the alpha from a PNG image was a preprocessing step it wrote by itself as part of a larger task I had given it, so it certainly understands transparency.

I even often describe the results e.g. "this fails when in X manner when the image has grainy regions" and it figures out what is going on, and adapts the code accordingly. (It works with uploading actual images too, but those consume a lot of tokens!)

And all this in a rather niche domain that seems relatively less explored. The images I'm working with are rather small and low-resolution, which most literature does not seem to contemplate much. It uses standard techniques well known in the art, but it adapts and combines them well to suit my particular requirements. So they seem to handle "novel" pretty well too.

If it can reason about images and vision and write working code for niche problems I throw at it, whether it "knows" colors in the human sense is a purely philosophical question.
