Description
This package implements the HSLuv color space model, providing a perceptually uniform alternative to traditional HSL. It includes functions for converting between HSLuv/HPLuv and other color spaces like RGB, XYZ, LCH, and LUV, as well as hexadecimal color representation.

Description
This OCaml package implements the HSLuv color space model, providing a perceptually uniform alternative to traditional HSL. It includes functions for converting between HSLuv/HPLuv and other color spaces like RGB, XYZ, and Luv.
The HSLuv color space is particularly beneficial in scenarios where perceptual uniformity and intuitive color manipulation are crucial:
Design and Visualization: Ideal for creating balanced and harmonious color palettes with consistent hues.
Data Representation: Useful in data visualization for accurate and non-misleading representations, such as in heatmaps and graphs.
Accessibility in User Interfaces: Helps in maintaining consistent contrast, crucial for users with visual impairments.
Digital Art and Image Processing: Offers fine-tuning of colors for subtle and precise adjustments.
In summary, HSLuv's appeal lies in its ability to provide visually consistent and natural-looking colors, making it suitable for design, data visualization, and artistic applications.
Implementation Notes
This started as a port of the Go implementation of hsluv.org.
The following color conversions are provided:
| From/To | HSLuv | HPLuv | RGB | XYZ | LUV | LCH | HEX |
|---|---|---|---|---|---|---|---|
| HSLuv | - | - | hsluv_to_rgb |
- | - | conv_hsluv_lch |
hsluv_to_hex |
| HPLuv | - | - | hpluv_to_rgb |
- | - | conv_hpluv_lch |
hpluv_to_hex |
| RGB | hsluv_from_rgb |
hpluv_from_rgb |
- | conv_rgb_xyz |
- | conv_rgb_lch |
conv_rgb_hex |
| XYZ | - | - | conv_xyz_rgb |
- | conv_xyz_luv |
- | - |
| LUV | - | - | - | conv_luv_xyz |
- | conv_luv_lch |
- |
| LCH | conv_lch_hsluv |
conv_lch_hpluv |
conv_lch_rgb |
- | conv_luv_lch |
- | - |
| HEX | hsluv_from_hex |
hpluv_from_hex |
conv_hex_rgb |
- | - | - | - |
In addition to the HSLuv and HPLuv conversion functions, this package also exposes
color conversion functions between the various color spaces used to enable the HSLuv and HPluv conversions
pretty printers
pp_hsluv,pp_hpluv, etc.a library
hsluv.float_convfor conversions between float triples and the provided color types
Tests
The implementation is tested against the hsluv snapshot (revision 4). Tests for all conversion functions are included and can be run with
opam exec -- dune test
