The iPad version now stops the active sound when a new one is triggered, ending the cacophonous effect. The iPhone version now clears the label on scrolling ensuring a clean view.
Early this morning I submitted Color Explorer 1.1. This version is Universal, meaning it will also run on iPhone and iPod Touch. It also corrects a minor issue by clearing the item labels whenever a new color is loaded.
I'm pretty happy with the iPhone/iPod Touch version. I'll post again once it's been approved.
