Making an is_color function

[tibberous]

I need a function that takes a color and returns true for false depending on whether or not it is a color.

 

I want it to support the following formats:

 

#000

#FFFFFF

rgb(255, 255, 255)

All the color names: http://www.javascripter.net/faq/colornam.htm#top

 

Basically it is three semi-easy regex expressions and a big array with an in array check. I was wondering if there was already one written, I Googled but couldn't find anything.

 

Thanks

Probably not, since those are three very different color formats. You might want to write each one as a function and then have one large function that checks each.
