Colour
Pulled from the resistor colour code — the native colour language of a parts drawer, and the reason the palette can carry information, not just mood.

The one asset 100% of America still recognises, re-cut hotter and cleaner for screens.
The ink. Anodised-housing black — every tool on the bench is this colour.
The ground. Brushed metal and spec paper: warmer than white, never cream.
The material inside every cable. Carries the warmth in packaging and print.
Fuse yellow. Live states, queue times, warnings, the repair counter itself.
Specs, rules, secondary type. The quiet 90% of any technical layout.

Red is a punctuation colour, not a field colour — the shopfront fascia and the
cover of a pitch deck are the two places it goes full-bleed. Everywhere else
it earns its 16% on the mark, one headline word, and the price.
