Well, I'd would need what you are trying to do, to make suggestions. I don't know how you're a telling to the AI what do you want.
But I can say one thing for sure. Even for a k-80, 6h is too much. I made tests and, 80% of times, images don't improve after 500 iterations. Eventually some improve until 1000 iterations or so, and time to time, until 1500.
Again, tell me more about what you are trying to do, and I'll try to help.
Take this !PIZZA by the way!
@aemile-kh! I sent you a slice of $PIZZA on behalf of @jotakrevs.

I use VQGAN+CLIP method, imagenet_16384 and promt without init image. Turned out if I ask for a specific color a quality of image drops significantly. Idk why. It's very noisy and edges too sharp. But now it's much better when I don't ask for a specific color.
Thank you for !PIZZA it's delicious!
To get a particular color asking for it to the AI doesn't work well, as you can see. You could try to add to your prompt, an artist who painted a lot of stuff in the color you like, and in a style that you like. I didn't make experiments to try to force the AI to use particular colors yet, so is not like I can say you anything else, sorry!
