This is new transflective daylight display technology and no it does not have to be backlit to have color. I have a 4 inch color transflective lcd on my bench right now. The brighter the light the better it looks. I am getting a sample of one that has low power led backlighting that only adds about 8 to 10% more power consumption. The larger concern is the CPU does not have color support right now.
The app note even shows a photo detector circuit to automatically turn on the backlight in low light conditions
