I don't want to pronounce on sanity, but I don't think it has ever been a  
major criterion for whether people *will* do something on the Web.

And it seems pretty easy to make a colour picker in canvas. I can imagine  
that anyone who wanted a specific-purpose color picker (styled to match  
the site, or customising the options, or...) would do it in canvas or SVG,  
and my guess is the former would be more common...
