designlang 13.3.2 against Dembrandt 0.33.0

Run on 4 November 2026, one site at a time on the same machine, alternating which tool goes first.

A colour counts as right within ΔE 10 of an official brand colour that is actually painted on the homepage. Sites whose brand colour is not on the page are not scored for colour.

Primary colour right, designlang: 60%32 of 53
