spectr.pm vs tldraw

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

Ground and ink

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

spectr.pm

Heading on canvas

Body copy in the measured muted role.

Primary action
18.6:1 ink on canvas

tldraw

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.
