We are building a device based on a low-power CPU and we need to choose between a color back-lit LCD with a touchscreen and an "old-school" black and white LCD for the device. Obviously the user experience would be much better with the former, however, power consumption is a priority for us and in principle we can sacrifice user experience in case the black-white LCD saves us battery life considerably, i.e. for example 2 days vs. 5 days.
I'd appreciate if you could give me an insight into this. Am a software engineer myself.

By itself, an LCD being color or monochrome doesn't affect power consumption. Color LCDs are just monochrome LCDs with filters on the pixels to make them red, green, or blue. What will affect power consumption is:
You have to look at the display options in the context of the system to make a determination of the ultimate effect on battery life.
