Firefly disregards prompt completely, if there is some reference and style images added.
I never found Adobe Firefly to be of any use, I saw many designers being fearful of it replacing humans and all that.
I tested it in all permutations & combinations, but it was not able to generate images of even very very simple prompts of simple objects like a pastry. See my Screenshots below.


None of the pastry looks purple in color.
After every vague result, I shared the feedback with adobe too. But frankly I would rate firefly to be totally disregarding the user prompt.
