chromatic 0.1.4

Color science for Dart: conversions between sRGB, Lab, XYZ, LCH, HSL and more. Delta E, chromatic adaptation, proper sRGB EOTF.

Changelog

0.1.4

• Fix: 0.1.3 was published with a CHANGELOG that did not include its own version entry (pana flagged it as invalid). This release has a correct CHANGELOG. No other changes.

0.1.3

• Add .pubignore to exclude demo/, tool/, and .github/ from the published archive (0.1.2 accidentally included the demo Flutter app, bloating the download by ~50 KB). No functional changes.

0.1.2

• Point homepage at the new interactive demo site: https://enraio.github.io/chromatic/
• Add documentation link in pubspec.
• No code changes; ports, tests, and benchmarks are unchanged from 0.1.1.

0.1.1

• Shorten package description to meet pub.dev 60–180 character guideline.

0.1.0

Initial release. Port of Python colormath with identical math.

Added

• 10 color space types: sRGB, Adobe RGB, Apple RGB, BT.2020, XYZ, xyY, Lab, LCH(ab), Luv, LCH(uv), HSL, HSV, CMY, CMYK, IPT
• Color space conversions between all supported spaces
• Delta E formulas: CIE76, CIE94, CIEDE2000, CMC l:c
• Chromatic adaptation: Bradford, von Kries, XYZ scaling
• Proper sRGB EOTF (piecewise, not simple power gamma)
• Proper BT.2020 transfer function
• Hex parsing (6-digit, 3-digit shorthand, with or without #)
• 11 illuminants for 2° observer, 4 for 10°
• 690+ test fixtures validated against Python colormath output
• Sharma 2005 CIEDE2000 reference dataset (34 pairs) integration tests
• Benchmark suite comparing against Python colormath
