When developing web site, I often needed color picker tool to find the exact color that I want or to find exact color a designer want me to apply. Quite a long time, I was using color picker plug-in in Chrome, which was useful at least to use for web pages inside of a web browser.
But, from some point in time, I realized that I need to pick a color out of web browser, literally anywhere in monitor. So, I googled and could found one color picker utility easily.
That was ‘ColorPic’, which is small and simple but works just as I wanted. After using this once, I decided to stick to it.
