The Color palette in Photoshop (see screenshot) is, to be charitable, a bit long in the tooth. In particular, the little color ramp at the bottom is awfully small (occupying just 0.00072% of the screen real estate on at 30" monitor; yes, I did the math).
We certainly won’t break what’s working or force you to use a larger color picker than what’s there today. Having said that, there’s clearly room for some innovation.
What kind of color-picking tools would you like to see in Photoshop? Are there good examples you can share? We’ve already batted around the idea of revealing kuler-like functionality in Photoshop (see very rough mockup). What else would be cool/useful/powerful?
