Hmm that’s true for me too. Not sure if it is due to resource constraint. I had a picture of a car in indoor parking lot with walls and pillars. When I prompted “Color the car blue” the whole image was drenched in a tint of blue. Similarly when prompted “make a hummingbird hover” … the hummingbirds were a patch of shiny colors with an shape that sort of looked like an hummingbird but not like a real one.

Try "turn the car blue"

Does dalle do prompt based photo edits now?

But yeah sometimes it doesn't follow directions well. I haven't noticed a pattern yet for why that is.
