Color

A bright canvas, one living green, a data blue and honest flags. Semantic colors only ever mean what they say: coral is high, violet is low, amber is "keep an eye on it".

Type

Bricolage Grotesque carries headlines with character. Instrument Sans keeps body text calm and legible. Instrument Serif italic adds one warm word per headline, never more. JetBrains Mono labels data, times and eyebrows.
