I don't think this app is as bad as some of the earlier comments suggest. First off, it launches and runs just fine on my 3GHz quad-core Mac Pro with OS X 10.6.4. If it won't launch, chances are there is something wrong with your system - perhaps you haven't kept Java up-to-date.

The interface now includes the basic Mac UI elements: window management buttons, a window resize zone in the lower right-hand corner and the basic OS X graphite appearance [note that the screen shot on MacUpdate is not up to date]. Colorspace utilizes a unique version of the color wheel including the primary, secondary and tertiary colors with tints and shades and a dozen zones in between the twelve standard colors. Working with these 120 initial hues, you can adjust the saturation and brightness to achieve any number of variations. With the Capture Color tool you can pick up color from anywhere else on your screen. Color values are displayed in HTML Hexadecimal or RGB decimals and can be limited to web safe colors.

The program works just fine in demo mode where I've been testing it; whether the licensed version is worth $30 to $35 will depend on whether it meets your color selection needs. But the developer has made an effort to make the Mac version look and work like a Mac application. It no longer has that androgynous Java appearance it started out with - which renders many of the early criticisms moot.

In the description it says "the application can be hidden in the task bar" (As of 12.20.09). They want to actually SELL this to Mac users? C'mon man, write a real Mac app that respects Mac users and OSX. This ugly Java crossover Windoze port just won't cut it in the Mac world. The standards here are higher!

Written in Java, looks like Windows. No thanks.
