Project under development (2018). This is a color picker, which mimics the one from Photoshop (with RGB, HSB, Lab, CMYK, web colors filter), implemented in JS/WebGL, with a new feature that let you know the name of the closest HTML/CSS color (cf. w3c).
At this stage of development, the software has only been tested on Google Chrome, on the Macintosh. Please use Chrome to test.
You can try it here.
Here are some screenshots to illustrate some features:
