In my early days as a designer, I really struggled to get the hex codes of some of the colors that I liked from some websites or when I needed to base my website colors based out of the logos provided by clients. What I used to do was trial and error method to get somewhat accurate color matching and it was really painstaking and time taking process. Then I learned about color picking tools and I experimented with a few of them and I must say, Colorzilla is pretty much the best color management system I’ve used on any browser. The color sampling is accurate and consistent across sites. The most useful feature that I’ve found to be really handy is the picked color history feature which makes colors I’ve chosen in the past a breeze to re-use.
