Always generating gradient

[Ajda0101]

Firefly is continuously generating background with a gradient, even when the prompt specifically instructs no gradient (with various versions of the prompt).

Hello @Ajda0101,

Thank you for your message. I am sorry you are having this problem. 

The model does not understand the concept of a word being negated by the word in front of it. So using "not [X]", "no [X]", and "without [X]" does not work. As you observed, it ignores the negation word and add to the image the thing you are trying to avoid.  You basically need to find "positive" words and phrases telling the model what you want to see rather than telling it what you do not want to see.  Such as "flat land" rather than "no mountains".  If I am not sure how to describe something I want to exclude in a positive way, I will ask Google Gemini or ChatGPT for ideas.  Just be aware that when they give prompts, they are usually too wordy and conversational, so you have to edit them, but they are good for ideas.

In your case, I would use something like "solid colour".

Thanks,

That's a great hint regarding negation. However, even when trying to use only positive prompts, it still forces gradient (example attached, prompt: "The most simple image of a circle. Use two solid, uniform colors, #4290f5 and #f2a813.). It seems there's not way to avoid this.

Try using "flat" or using the Flat Design style from the options on the left:

The most simple image of a circle. Use two solid, uniform colors, #4290f5 and #f2a813; Flat art.

With the Flat Design style checked:
