Prompt pattern
Set a welcoming base with warm off-white
Cream or warm grey gives a site softness while preserving a clear contrast for text and actions.
Fills the background part of a prompt.
Use a cream, sand, or warm grey base across the page, then pair it with dark charcoal text and one earthy action colour. Separate major content areas with a slightly lighter or darker version of the same family rather than stark white. Do not combine it with cold blue-grey panels that make the palette feel accidental.
Use this background pattern when it changes the result the agent should produce. It provides one concrete direction without deciding unrelated parts of the website.
