Golfed down by 11 characters. Can someone make this green?

u/magna

Can shave another 2 by: i=半=500
u/magna

Need to shave another 11 to fit c.style.background='#0f0'. Playing with x.fillStyle could be more expensive because of the need to switch back to black.

Shaved down to 119: https://www.dwitter.net/d/2376
