This is a handy dandy color picker utility program, written as a web app. It is designed for laptop/desktop use, doesn't fit on a mobile device.

You can select a starting color by either selecting from one of the named web colors, or one of the 700 Mark Ferrari superstar pixel artist color swatches, then you can explore nearby colors which are arranged in a novel hexagonal grid that lets you explore in 12 different directions at once.

When you select a color, it copies the color name to the clipboard so you can paste it into what you are working on. There are multiple output formats you can choose from, like web hex #AABBCC, or rgb(1,2,3) for example.

Free. The 1400 lines of code is posted on GitHub, if you are curious as to how it was made. There are some clever tricks in the code regarding how to sort colors properly.
