This is a simple, flexible color-picker widget. It has no dependencies (not even on jQuery), so it's easy to just plug in and use. It weighs less than 3kb of combined JS & CSS once minified and gzipped. Since it exposes itself via the UMD exports format, it will comply with whatever module loading system you're using. If you're not using one, it will expose a global called EightBitColorPicker.
