Husl

A Ruby implementation of HUSL.

Installation

Add this line to your application's Gemfile:

gem 'husl'

And then execute:

$ bundle

Or install it yourself as:

$ gem install husl

Usage

husl_to_hex(hue, saturation, lightness)

hue is a float between 0 and 360, saturation and lightness are floats between 0 and 100. This function returns the resulting color as a hex string.

husl_to_rgb(hue, saturation, lightness)

Like above, but returns a list of 3 floats between 0 and 1, for each RGB channel.

hex_to_husl(hex)

Takes a hex string and returns the HUSL color as a list of floats as defined above.

rgb_to_husl(red, green, blue)

Like above, but red, green and blue are passed as floats between 0 and 1.

For HUSLp (the pastel variant), use huslp_to_hex, huslp_to_rgb, hex_to_huslp and rgb_to_huslp.
