xkcd color picker 0.1.0
A uniquely designed HTML5-based color picker
What this means is that colors can be selected via a text input field, besides the classic way of just pointing to the desired color.
The user only has to type in his desired color and a list of color name suggestions will appear in a drop-down.
He can then select one and tweak its RGB or HSL values to the value it sees fit.
For the selected color, similar and dissimilar color variants are also shown, just for variety's sake.
