Generate random Hex color

function genHexColor() { return '#'+(Math.random()*(1<<24)|0).toString(16).concat('000000').slice(0,6); }
Call the genHexColor() function to obtain a random color in Hex format.
///
Latest version: Prevents the function from returning hex strings shorter than 6 characters.

shorter one~
`'#' + (Math.random() * (1<<24) | 0).toString(16)`
@Rplus That is an absolute amazing trick! Thanks!
@Yarmo Mackenbach I learn it from the gist: https://gist.github.com/addyosmani/fd3999ea7fce242756b1
@Rplus Yeah but it'd end up with missing 0 digits sometimes, I tried it in the nodejs console.
@Luis Lopez It did! Good point, @Luis Lopez! So I made a new version, and this one automatically adds zeroes <i>.concat('000000')</i> and then truncates whatever is too much <i>.slice(0,6);</i>. The last version is fool-proof!
