OK Chris, The vOICe Java MIDlet runs fine on the Nokia 6600 too, albeit a bit more sluggishly because its processor runs at only 104 MHz, whereas the Nokia 6630/6682 run at 220 MHz. In fact, I have a Nokia 6600 myself and use it for software testing.

The vOICe color identifier ought to work about as well as the Code Factory color recognizer, with further options (color filters with soundscapes) to find items of a chosen color in your camera view - e.g., try finding a green or red pepper. You may need to mute or pause The vOICe to let your Mobile Speak screen reader speak The vOICe menu, as CPU load may otherwise effectively stop the screen reader from speaking the menu items. All of this is documented on my web page (URL in my signature).

I have a Nokia 6600 (it is Symbian Series 60 like those you mention) and an HP iPaq 6515 PDA/Phone which runs Windows Mobile 2003 which is not compatible with either desktop Windows or Symbian. I have the code Factory color recognizer on my phone and it works very well.
