v1.6.1 — Auto-finish explore on exact match

Explore mode now automatically ends the round when you guess the exact colour, instead of letting you continue guessing. Thanks to user feedback for catching this!

v1.6.0 — Meodai colour palettes

Integrates meodai/color-names — a community-curated collection of over 30,000 handpicked colour names.

New palettes

• Meodai (~4,300 curated names) — included in the default "All" pool, roughly doubling it from ~3,300 to ~7,600 colours
• Meodai Full (30k+) — opt-in only, not in the "All" pool or daily rotation

Other changes

• Daily "All" picker prevents the same source appearing twice in a row
• Clickable (i) info badge on the source label during gameplay with per-palette descriptions
• Updated about page with palette docs and meodai credits

v1.5.3: Fix DST bug in daily puzzle numbering

Fix daily puzzle number repeating after DST spring-forward.

getDailyNumber() used local-time Date objects for millisecond arithmetic, which loses an hour across DST boundaries. Switched to Date.UTC() for the day-count arithmetic — the standard DST-safe approach for calendar date differences in vanilla JS.

v1.5.1 — Percentile fix & input placeholder

Hotfix for percentile display and UX improvement.

Fixes

• Percentile display: Was counting the player themselves in the comparison pool ("you beat 2 out of 2 players" when there were only 2 total scores). Now correctly excludes self — "you beat 1 of 1 player"
• Top 0%: Clamped to minimum "Top 1%"
• Pluralization: Proper singular "player" vs plural "players"

Changes

• Input placeholder changed from ... to write a colour name here for better discoverability

v1.5.0 — POEM-based name scoring

Name scoring now uses the same POEM consensus as matching — all six distance measures rank every colour name by similarity to your guess, and the target's rank determines your score via a quadratic curve.

What's new

• Word order doesn't matter — "gray sky" scores 100 against "Sky Gray" (was ~56)
• Typos more forgiving — "cerulian" → "Cerulean" scores 100 (was ~86)
• Quadratic curve rewards top positions, penalises distant matches: top 1% → 98, top 10% → 81, top 50% → 25
• Updated about page with new scoring formula

Why

Matching and scoring now use the same algorithm. If POEM thinks your guess is close, you get rewarded for it — no more penalty for word swaps or minor spelling variations.

v1.4.1 — Behind the Matching

Add an interactive Behind the Matching page that lets you compare Colourdle's POEM adaptation against the original paper's fitness-based selection, side by side.

What's new

• Both algorithms run in-browser on all ~3,300 colours
• Shows top-10 matches, per-measure distances, and timing
• Linked from the about page's "How Matching Works" section
• Try "gingerbread" for a case where the approaches disagree

Based on Brereton et al. 2020.

v1.4.0 — POEM-based Pareto matching

Replace simple Levenshtein matching with POEM (Pareto-Optimal Embedded Matching), a multi-measure consensus algorithm adapted from Brereton et al. 2020.

What's new

• 6 string similarity measures: Levenshtein, word-sorted Levenshtein, bigram Dice, word Jaccard, substring containment, word containment
• Pareto front selection with mean distance tiebreak — no single measure can outvote the consensus
• Top 50% pruning per measure before dominance computation
• Zero external dependencies
• "gray sky" now correctly matches Sky Gray instead of Gray Sand

Technical

• Updated about page documenting the algorithm with published citation
• PR review fixes: Pareto correctness, consistent Set usage in Jaccard, empty pool guard

v1.3.5 — Pirated movie subtitle source label

Source label (XKCD, CRAYOLA, etc.) moved from tiny chrome bar text to massive white-on-black burned-in subtitle styling above the input field. Impossible to miss.

v1.3.4 — Total → Final on summary screen

Also changed "Total" to "Final" on the summary totals row (missed in v1.3.2).

v1.3.3 — Top X% percentile format

Percentile now shows "Top 25% (you beat 3 out of 4 players)" instead of "Better than 75% of 4 players".
