Loose painting to define areas of an image.

Oftentimes when creating an illustration you are working with various requirements. For instance you have to leave room for a headline or the client’s product, or you have two figures fighting and want their swords to cross in just a certain way. Blocking-in the illustration lets you paint a broad stroke or lump of color for each of the elements in your prompt. Each element gets a different color and then you can prompt with <red> or <blue> tags to let the AI know where the elements go in the prompt. This is a really useful tool and takes AI from “hoping you get something useful” to creating an image that fits a requirement. All jobs have requirements.
