Xenon OS

This is not an actual OS,  it just emulates one.

Tips:

Press a number 0-9 for colors in the paint app (only the version 1.2.0+)

Press - or = to decrease/increase paint size!

System requirements (these are likely inaccurate):

Minimum: 1GB RAM and a CPU with at least 2 cores at 1GHz clock or higher. (This is because of the browser's resource requirements.)
