Palette relationships

When a designer hands an agent a single starting hue and asks for "the rest of the palette," the choice is which relationship model to apply. Each model is a hue-angle pattern with a different emotional and functional register. Knowing the patterns is most of the job.

When to use

• A designer or agent has a starting hue and needs additional hues to fill a palette.
• Proposing a palette for a brief that uses words like "balanced," "vibrant," "calm," "tense," "restrained," "dynamic."
• Reviewing a palette proposal — name the implicit relationship and check whether the brief asked for it.

When NOT to use

• The palette is already specified (all hues given). Use chroma-harmonization to balance them, not this skill.
• The brief is for a single-hue system (just stops of one palette). No relationship to pick.
