Adobe happens to have the lion’s share of the graphics and web design software market. Since they also happen to be a fairly large shop and they’ve tweaked the look of their applications across releases, I’m assuming they’ve got a few GUI developers in the payroll. So how come they can’t fix little inconsistencies in their leading applications’ user interface?
For instance, start up Illustrator (in Mac OS X) and open a blank document of any dimension. Now in the System Preferences, change the Appearance of the Operating System from Blue to Graphite (or vice versa). 
Notice the discrepancies? Illustrator’s interface colors don’t change – or at least some of them. Hasn’t anyone at Adobe picked up on this?
