Data meaning
Signals
Green, cyan, violet, yellow, red — for status, not chrome.
Signals are for data meaning only: green, cyan, violet, yellow, red. They color status, alerts, and series — never buttons, never the wordmark, never brand chrome.
Chrome stays Spark orange. If a Source goes down, the last value stays and ages. Three failures turns it orange — the brand color, used as a warning, on purpose.
Read a board the way you’d read a wall: numbers in Geist Mono, health in Signals, attention in Spark.
