It looks like Delta will be painting a Boeing 767-400ER (my favorite airliner) in a pink livery for the Breast Cancer Research Foundation. This will replace a Boeing 757-200 currently in a different pink livery, which will be repainted into standard Delta colors. The reason for this is that Delta wants to spread the word of breast cancer internationally; the 757-200 that currently wears a pink livery only flies domestic routes.
Here is a rendering of the aircraft:
Looks pretty jazzy!
