// As it has been said a thousand times, great artists steal :) If you like the color palette used on a website, you can use Colorfy it to easily find out exactly what it is.
Given a URL it will analyze the source code of the #HTML and #CSS and provide you with a list of all colors used, their frequency and on which files they are mentioned.

And if you have any app ideas, Colorfy it also provides an open API without any usage limits.
