ColorJack itself isn’t anything new, but recently, the color theory visualization site has added a color sphere to further enhance color scheming. It adds a new level to an already interesting and useful site. ColorJack lets you export your chosen color palettes into Illustrator and Photoshop pallets, making it useful for all sorts of ideas. It also can restrict colors to various types of color blindness – a pretty nifty feature. And if nothing else, playing with color wheels is always fun.
On a side note, it’s possible that I’m merely drawn to ColorJack because their logo looks an awful lot like the now-defunct Genetics Shoes logo, which has always had a special place in my heart.
