The ColorParser gem provides a simple way to parse the colors from an HTML page. It scans both the HTML and CSS to find all colors and sort them by frequency used.
Get colors on a given webpage
page = ColorParser::Page.new("http://google.com/")
colors = page.colors
=> {"ffffff"=>5, "c9d7f1"=>1, "0000cc"=>2, "dd8e27"=>1, "990000"=>1,
"3366cc"=>3, "000000"=>2, "1111cc"=>5, "cccccc"=>2, "551a8b"=>1}
colors = page.colors_by_frequency
=> ["ffffff", "1111cc", "3366cc", "000000", "cccccc",
"0000cc", "dd8e27", "c9d7f1", "990000", "551a8b"]To install ColorParser, add the gem to your Gemfile:
