However, it is not an online tool, but to use it you must download it to your computer. From then on, all you have to do is move around the image and hold down the left mouse button on the tone you want to identify. When released, there will be copied to clipboard. A way to streamline a process that can become somewhat tedious if we repeat it too many times.


One of our favorites, Swatch Matic is an interesting application for Android that allows us to identify any color that surrounds us instantly. It does through the camera of our device, through which it captures and identifies the different colors.

Although it is something a bit different, Colorize is another application that deserves to be included in this list, as it is an interesting project developed by Alex Beals that also helps us find the “true color of things”. In any case, it does it in a different way, since it is focused on those who get hysterical when they hear that of “off white“,” Sand “, or” terracotta “.

Indeed, because what this page does is allow us check what we are talking about exactly when we refer to these colors. To test it, we only have to enter the name (yes, in English) to know the tone to which we are referring. Fun and useful.

But, Where does the result come from? It is random? Not much less. What Colorize does is automatically search for the word entered on the Internet and analyze the first 25 images and their color codes. Moment from which it carries out its particular average and shows us the result in question.
