Hex

• IBM Plex stack (Sans + Mono) as the typographic spine — the implicit acknowledgement that data scientists already trust this family from Jupyter and academic publishing.
• Cinetype as a display foil — appears in headline moments to lift the IBM Plex baseline without disrupting its authority.
• Viridis-adjacent accent palette (#22863a → #5ec962 → #addc30 → #fde725) — exact colours a data analyst would generate from matplotlib's default colourmap. This is taste expressed through implicit reference.
• Pure #000000 ground (~508 surface refs) paired with #01011b near-black text — the navy-tinted black gives the page a printed-page feel rather than absolute dark.
• Single 1000px container — tight magazine reading width, perfect for code blocks and inline data visualisations.
• 7 catalogued gradients used for subtle data-viz atmospherics, not decorative chrome.
• Editorial typography stack with PP-Formula and PP-Editorial New preloaded — Hex commissions display fonts most teams wouldn't reach for.

• How to signal data-scientist credibility through typography alone — IBM Plex isn't a fashion choice, it's a peer signal. Steal the implicit credibility of using fonts your audience already trusts in their own tools.
• Viridis colourmap as brand palette — Hex didn't invent the green-to-yellow ramp; matplotlib did. Choosing to inherit it tells data scientists 'we ship the same defaults you do'.
• Editorial display stack on a technical product — PP-Formula + PP-Editorial New + Cinetype is a magazine typography stack. Most data tools don't bother. Hex's investment in display fonts reads as serious editorial design culture.

• Don't ship IBM Plex without committing to both Sans AND Mono — the relationship between them is the brand. Picking just Sans flattens the editorial-meets-code feel.
• Don't lift the viridis accent ramp without owning the data-viz context — out of context, the green-to-yellow looks like a traffic light palette. The colours work because the audience reads them as colourmap defaults.
• Don't widen the 1000px container — Hex's reading rhythm depends on the magazine-density of code blocks and inline charts at that width.

The page feels like reading a well-edited data-science quarterly — every code block is laid out as if it belonged in a Tufte chapter, every accent colour is recognisable from a matplotlib import, every section is timed at the cadence of a thoughtful tutorial. The brand's secret is that it has no marketing voice — it has an editorial one. Hex sells data work by looking like data work, which is a far harder discipline than it appears.

• Direct heir to the editorial-technical school that Tufte's Visual Display of Quantitative Information established — Hex is what happens when that visual literacy meets a venture-funded product team.
• Standing shoulder-to-shoulder with the modern data-notebook peer cohort (Observable, Mode, Deepnote) — but Hex has the most assertive editorial display stack.
• Part of the IBM Plex typographic wave that includes Cloudflare, MoMA's digital identity, and the broader 2020+ open-source-corporate aesthetic — Hex carries that genealogy forward in the data space.
