CssColour

Ruby CSS Colour validator.

It will tell if a colour is either:

• inherit,
• HEX #123 or #123123,
• HSL,
• HSLA,
• RGB or
• RGBA

A couple of guidelines were used here:

• MDN's docs,
• this Ruby HEX validator and
• these Java regexes for HSL/RGB/RGBA were adapted to Ruby and made more readable.

Add this line to your application's Gemfile:

gem 'css-colour'

And then execute:

$ bundle

Or install it yourself as:

$ gem install css-colour

validator = CssColour::Validator.new 'inherit'
validator.valid? # true

You can also test against a specific colour type as follows:

validator = CssColour::Validator.new '#123456'
validator.rgb? # false
