AI Art Generation Handbook/Negative Prompts

Negative prompts work by providing the AI algorithm with an input that it needs to avoid.

Negative prompts in Stable Diffusion can be compared to a painter’s palette of colors. Just as a painter selects colors from their palette to create a painting, when using Stable Diffusion's negative prompts to exclude certain elements from the final image.

For example, if the prompt crafter wants to create a portrait without any green color in it, they can give a negative prompt that instructs the AI algorithm not to use any green color, therefore the AI Art generator will try their best not to use any green colors in painting.
