railway.app vs www.uber.com

Two design systems side by side, measured from the live sites — colour, type, shape, depth, components, states and responsive behaviour.

Worth knowing

  • Neither side has named colour roles, so both predate role-based extraction. Re-generating either one fills in the palette comparison.
  • Interaction states are missing on at least one side — that site's stylesheets were cross-origin and could not be read.

Ground and ink

Each side painted in its own measured canvas, ink, muted and primary roles.

railway.app

No colour roles measured on this side, so there is no ground to paint. The palette below is still real; re-extracting the site fills this in.

www.uber.com

No colour roles measured on this side, so there is no ground to paint. The palette below is still real; re-extracting the site fills this in.

Palette

Named roles first, then every colour measured without one.

Type scale

Set at the measured size, weight, tracking and leading. Brand typefaces are not loaded, so the metrics are real and the letterforms are not.
