Keep a compact palette for rapid selection and a full-screen picker for detailed work.
Present the fixture capability status prominently (icons for RGB, CMY, white, wheel).
Use numeric readouts (RGB, HSV, Kelvin) alongside the visual picker for precision.
Drag-and-drop color swatches onto Executors or playbacks to create stored actions quickly.
Provide keyboard shortcuts for cycling through recent colors and toggling modes (e.g., sample, apply-as-palette, apply-live).

Developer integration checklist

Read/write Palettes and Cue parts using the grandMA2 remote API.
Query selected fixtures and capabilities via fixture list API.
Provide fallback mapping when fixture profile data is missing.
Lightweight image processing (k-means, color quantization) that runs on-console or a connected PC.
Localization for Kelvin units and numeric formats.
