Colr.org is an online tool that helps you pick a scheme color from an image, and even from a webpage! Yeah, I really mean it. You just have to type the url of a webpage whose scheme color you want to pick then clik “fetch colors” and voila…! You’ll get it right away.

Corl.org also allows us to expand a color scheme and find the similar one. If you want to make use of these excellent functions, it’s simple, you can use the API provided.

Colour Contrast Check is an online tool that helps you choose which foreground colour is suitable with your background colour and which is not. You can manage the colour by adjusting the Red, Green, Blue, Hue, Saturation and Value provided.

The result of your adjustment determines whether the Brightness Difference >= 125 or not, the Colour Difference >= 500 or not, and the two colours (background and foreground) are compliant or not. It also determines the value of Contrast Ratio.
