A control-room design language: dense telemetry on near-black glass, one resting green, and a housing around anything that matters.
Colour carries state and nothing else. Each signal has a job, a hex value and a contrast ratio against the ground, and none is allowed to do another's work.
The resting data state. Values, labels in good standing, the live trace.
15.0 to 1 on the ground
Emphasis and interruption. It arrives as a block, never as a coloured word in a paragraph.
10.8 to 1 on the ground
Reserved for the one alarm that matters, always with a label and an icon beside it.
7.5 to 1 on the ground
Tight inside a bay, generous between bays. The same deck holds from a 390px handset to a wall of 2560px glass.
