The ColorSchemer guys have done a great job at listing all the browser-supported colo(u)rs by their name, rather than their Hex or RGB value.
If you are a coder, like me, it is a great reference for quickly picking colours when mocking up a web application.
I’m now a fan of ‘lightgoldenrodyellow‘ and ‘dodgerblue‘ -where did that name come from?
(Thanks to for the links).

But why is ‘darkgray’ darker than ‘gray’?
