Every palette ships with roles assigned — surface, support, primary, accent, ink — plus its contrast record. Copy it and you have a working theme, not five hex codes.
Teal reads as "monitoring", not "alarm". The single coral is reserved strictly for critical states, so red means red and nothing else does.
A slate-blue dark surface with one cyan primary. The accent is loud so status and alerts read at a glance against the calm chrome.
Indigo carries every chart series; the surface stays paper-white so dense tables never feel heavy. One warm amber marks the outlier.
Five steps of one cool grey. Charts borrow saturation only where a series needs to be told apart.
