Bumps github.com/lucasb-eyer/go-colorful from 1.2.0 to 1.4.0.

Release notes

Sourced from github.com/lucasb-eyer/go-colorful's releases.

v1.4.0

This release adds support for CSS Color Level 4 wide-gamut RGB color spaces, along with D50 XYZ helpers and a small HexColor usability improvement.

Added

• Constructors, decomposers, and blend functions for the CSS Color Level 4 wide-gamut RGB color spaces DisplayP3, A98Rgb, ProPhotoRgb, and Rec2020 (#81)
• XyzD50, Color.XyzD50, D50ToD65, and D65ToD50 for working with D50-based color spaces (#81)
• HexColor now implements fmt.Stringer

v1.3.0

If you'd like to support go-colorful's development you can support me or Lucas (the original developer) through GitHub Sponsors, check out the Sponsor button up top. I also have a Ko-Fi for one-time donations.

The rest of this message is copied from the CHANGELOG.md file in this repo.

Added

• BlendLinearRgb (#50)
• DistanceRiemersma (#52)
• Introduce a function for sorting colors (#57)
• YAML marshal/unmarshal support (#63)
• Add support for OkLab and OkLch (#66)
• Functions that use randomness now support specifying a custom source (#73)
• Functions BlendOkLab and BlendOkLch (#70)

Changed

• Hex() parsing is much faster (#78). However, it doesn't tolerate hex codes with alpha anymore (previously ignoring the alpha was unintentional).

Fixed

• Fix bug when doing HSV/HCL blending between a gray color and non-gray color (#60)
• Docs for HSV/HSL were updated to note that hue 360 is not allowed (#71)

Deprecated

• DistanceLinearRGB is deprecated for the name DistanceLinearRgb which is more in-line with the rest of the library
