“DJ App for iPad.” For you wannabe DJ’s out there.
“Colors takes Apple’s basic color chooser (complete with “magnifying glass” to pull colors from other applications), and combines it with an easy way to copy common formats of color values (eg., #rrggbb, rgba(r, g, b, a), etc.) to the clipboard.” It’s a little ways down the page (I couldn’t find a more direct link) but it’s great (and free). I’ve wanted something simple like this for years, since I’ve been using the digital color meter because it’s packaged with OS X and fairly simple. The only problem was that I’d have to remember the hex value for Photoshop. Which, while a nice little memory game, gets old fast. Simple, lightweight, beautiful and dead simple.
