[3.0.0] - 2026-07-20

Breaking Changes

• Channel-range corrections (entry corrected 2026-07 — it originally claimed v2 normalized all spaces to 0–1; it did not: v2 already used conventional ranges — rgb 0–255, hsl 0–360/0–100/0–100, cmyk 0–100, ycbcr 16–235 — and those are unchanged). Five spaces rescaled to conventional form: hsm and tsl (were all-0–1), hsi/hcy/hsp third channel 0–255 → 0–100 (hsp also no longer rounds its outputs). Declared bounds made truthful where the v2 metadata understated the formula (lab a/b ±125, luv ±215, …) — metadata only, outputs identical. Spaces new in v3 adopt CSS conventions: predefined-RGB (P3, Rec.2020, A98-RGB, ProPhoto) are 0–1 per the CSS color() function; OKLab/OKLCh/OKLrab/OKLrch native 0–1 / ±0.4 (oklch.rgb(0.65, 0.25, 180) ≡ CSS oklch(0.65 0.25 180)); JzAzBz/JzCzHz and ICtCp native (Jz/I 0–1, az/bz/Ct/Cp ±0.5), matching colorjs.io / Safdar 2017 / BT.2100.
• Flat channel arguments: conversions take individual arguments — rgb.lab(10, 20, 30) — not an array rgb.lab([10, 20, 30]). (The array call returns as the batch form — see Added.)
• Space object shape change: .min, .max, .channel, and .alias properties removed from space objects; replaced by .range.
• Lab/LCHab are now D50 (ICC/CSS convention; v2 lab was D65). lab-d65 added for the v2-equivalent display-native Lab.
• ciecam (cam) removed — the v2 one-way stub is superseded by the full bidirectional ciecam02.
• cubehelix removed — a colormap (a single fraction painted to a color), not a color space you convert between; out of scope (README "What it isn't"). No replacement.
• rec2100-pq / rec2100-hlg ship hyphenated (corrected 2026-07: previously listed as a rename — the unhyphenated files existed only in unreleased dev builds, never in a published v2).

See https://github.com/colorjs/color-space/blob/master/docs/migration.md for the v2→v3 upgrade path, verified against the v2.3.2 source.

Added

• GLSL/WGSL shader chunks for all 161 graph spaces, including LUT-backed Munsell. A chunk is pure data ({ name, deps, edges, code }, like three.js ShaderChunk); color-space/gl is the engine that composes it — the engine imports the data, never the reverse. Import the spaces you convert and name the conversion: glsl(oklch, 'rgb') → vec3 oklch_rgb(vec3 c), the scalar library's shape one level down (cf. oklch.rgb(l, c, h)). glsl(oklch) bundles both directions; glsl(oklch, p3) routes a pair through their shared ancestor.
• Lean by default: a per-space import brings only its own dependency chain (~5 kB minified), not the ~200 kB catalog — and stays pure data (oklch.code is its raw GLSL for hand-embedding), so importing a chunk never drags the composer along. Byte-identical to the full catalog.
• Full-catalog tier color-space/gl/all routes any space by name — glsl('rgb', 'oklch') — for runtime from/to strings.
• Multi-conversion shaders: glsl([[a,b], [c,d], …]) emits every entry with shared chunks deduped — paint in one space, gamut-test in another, one source.
• WGSL for WebGPU, mechanically translated from the same chunks (wgsl(oklch) lean, color-space/gl/wgsl by name).
• GL differential suite: every edge evaluated as JS in float64 against the scalar library (test/gl.js), all 590 generated GLSL sources compiled on WebGL2 (test/gl-gpu.html), and all 590 translated WGSL sources grammar-parsed in CI (test/wgsl.js) plus live WebGPU validation when available.
• Complete reference coverage — all 161 graph spaces pinned to either the colorjs.io differential suite or a cited authoritative value (134 points), each entry carrying its source URL (test/bonafide.js).
• Integrity sweep: every composed pair callable as bare functions (catches this-bound conversion hops).
• meta.wiki — the canonical Wikipedia article per space (90 spaces; per-anchor verified), from a new @wiki JSDoc tag.
• meta.year / meta.by / meta.use — provenance (when the space was introduced, by whom) and usage domain + current status for 139 spaces, from new @year/@by/@use JSDoc tags (cross-checked against each file's cited references).
• color-space/wasm default export mirroring the scalar API: space.oklch.rgb(l, c, h) for scalars, space.rgb.oklch(buf) for whole buffers — an alloc()'d buffer converts in place (zero-copy), any other array-like returns a converted copy.
• color-space/lut: any conversion as a .cube LUT — cube(space.slog3, space.rec709) — for DaVinci Resolve, Premiere, Final Cut, OBS, ffmpeg. Channelwise pairs (pure transfer curves, e.g. rec709→rgb) auto-emit LUT_1D_SIZE 4096; cross-channel pairs emit LUT_3D_SIZE 33 by default (17/33/65 Resolve convention). Every header carries the measured deviation of the interpolated lattice against the direct conversion at random off-lattice points (median + max, fractions of full scale), so the file states its own accuracy.
• LUT differential suite against the scalar library plus an end-to-end ffmpeg check: the generated .cube applied to a float frame by ffmpeg itself must reproduce the library (test/lut.js, test/lut-ffmpeg.js).
• Shaper LUTs — cube(from, to, { shaper: true }) prepends the conversion's own tone diagonal as a 1D shaper (Resolve-flavor combined LUT_1D+LUT_3D cube; Resolve/OCIO read it): measured, a shaped 33³ beats a plain 65³ for camera-log → display at ⅙ the size (logc4→rec2020 4.1e-3 vs 5.7e-3); super-range clips at the shaper.
• color-space/icc — profile(space.p3) emits compact ICC v2 matrix+TRC display profiles for representable RGB working spaces; other bounded 1–4 channel spaces use sampled AToB/BToA CLUT profiles. Matrix colorants/TRCs derive mechanically from the space conversions and Bradford-adapt to the D50 PCS; output is pinned to Lindbloom/IEC values and host-verified through macOS ColorSync (test/icc.js, test/icc-colorsync.js).
• color-space/data.json — the registry as one language-neutral artifact: per-space metadata + conventional ranges, conversion-graph edges, gamut primaries, CIE whitepoints, the CIE 1931 2° color-matching functions, and the cited conformance triples the suite pins to (npm run data; registry-drift test-pinned like meta.js).
• color-space-mcp CLI (shipped by the color-space package) — zero-dependency MCP server over stdio JSON-RPC exposing convert/space/spaces/cube; driven end-to-end by test/mcp.js.
• Source-only repo, generated site — the website stages into _site/ (npm run landing → scripts/build-site.js: web/ sources + runtime modules with root-relative imports + prerendered catalog, a per-space reference page each, sitemap/robots/llms) and deploys via GitHub Actions (pages.yml, full suite as the deploy gate); web/ holds the site source, docs/ only markdowns. Generated package artifacts (data.json, types/*.d.ts, dist/, wasm/binary.js) are produced by prepare; prepublishOnly rebuilds and runs source plus packed-consumer checks before publication.
• Batch calling form on the JS hubs — every wired pair now also takes an interleaved array-like of pixels and returns a new Float64Array: space.rgb.oklch(pixels), for all 161 spaces. Stride follows each space's channel count (rgb→cmyk maps 3n→4n, kelvin→rgb 1n→3n), trailing params (ycbcr kb/kr) reach every pixel, and a batch of one is exactly the v2 calling convention — rgb.lab([50, 50, 50]) is legal again. Batch ≡ scalar pinned bit-for-bit across every pair (test/batch.js).
• color-space/lite — the compact hub: exactly the WASM-covered 27 spaces (rgb/lrgb/xyz, OKLab family, CIE Lab/Luv + DIN99, HDR, camera logs) in plain JS, ~9 kB gzipped vs the catalog's ~55 kB. Same registry shape, both calling forms, register() included — the three hubs (color-space, /lite, /wasm) interchange conversion calls freely (wasm is the bare kernel: range/metadata/register live on the JS hubs); parity with the wasm space list is test-pinned.
• WASM scalar kernels are true multi-value exports — each edge is rgb_lrgb(r, g, b) → (r′, g′, b′) (jz multi-value; i64 f64-bit lanes mapped by the jz:i64exp custom section), so the module's ABI mirrors the scalar API and scalar calls never touch the working buffer. Batch loops destructure the same kernels per pixel — each formula exists exactly once in wasm/batch.js — and the two forms are pinned bit-identical on every pair.
• Migration guide rewritten from verified v2.3.2 source diffs (https://github.com/colorjs/color-space/blob/master/docs/migration.md); linked from the README. The previous guide's central claim — "v2 normalized everything to 0–1" — was false (see the channel-range correction above), and its ×255 conversion recipes would have double-scaled correct v2 code.
• Identity conversions — space.rgb.rgb(…), scalar and batch, on all three hubs (MCP convert included).
• Machine-readable loss semantics — data.spaces.<name>.loss (projective / lookup / quantized) + lossNote tag the inherently non-invertible nodes: kelvin, cct-duv, maxwell, wavelength, gray, rg, cmyk, munsell, acesproxy.
• cct-duv, preserving both dimensions of near-white chromaticity as correlated colour temperature plus signed CIE 1960 uv distance; projective at conventional Y=100.
• Explicit legal-range Y′CbCr spaces for BT.601 525-line (SMPTE-C), BT.601 625-line (PAL/EBU), BT.709, and BT.2020 non-constant-luminance, fixing primaries, transfer, coefficients, and range in each id.
• Human-LMS maxwell graph space for fixed-observer trichromatic receptor-catch chromaticity.
