Prompt pattern
Blend several colour areas into one calm field
Multiple soft colour zones can make an opening feel rich without using a hard stripe.
Fills the background part of a prompt.
Blend 3 related colour areas across the opening section, keeping the centre behind the heading calm enough for readable text. Let one colour be noticeably quieter than the others so the page still has a visual resting place. Do not use a rainbow, sharp colour boundaries, or more than three dominant hues.
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.
