Color tone predictions based on location, orientation and timestamp.

[evitolins]

This might be out of the scope of this application, but throwing it out there...

I was thinking if you could provide or determine the location, date/time and orientation... you could more easily predict the appropriate tone of certain colors. Maybe it could even go so far as to determining the time of day based on shadow angles.

For instance, for your lighthouse example: Knowing the time of day would clue the app to determine the sky should be warmer, instead of assuming a blueish hue.
