KOBALT  Sounds okay, but without screenshots (even at the dev's website it doesn't show me what options the little drop down menu in the top right corner gives me) or any mention of the colour spaces it works in, I'll have to temper my enthusiasm.

VERYVITO  I've used Digital Color Meter and an "app-ized" version of the default OS X ColorPicker, among others, but this is what I've been looking for. Call me crazy, but I like menu apps -- one less thing to have to find and launch when I need it, so they fit well into my workflow, regardless of which app I happen to be using now.

The price is fair, too -- $5 is less than the cost of a sandwich, and something tells me I'll get plenty of use out of it. Tested and bought. (And on impulse, I also picked up the company's other app, Snippet, which may finally wean me away from using Stickies).

KRIS  Why is it when I go to view the "Help Docs" on the author's page, I get "404 not found?" This is not a good thing.

KRIS  I see the advantage of this product. At least it's big enough to see. In PS2, it's so hard to see the swatches panel.

I would like to know how I can use this while running PS2, especially with the eyedropper tool. Any suggestions?

MARK EVERITT  DigitalColor Meter comes installed (in your utilities folder) and has similar functionality.
