New Mercury photo in (false) colour!
NASA answered my question!
It's still "false colour" but it's a pretty decent stab at it. Lots of greenish blue around craters set against a pinky-browny-gray. Green could
be rusty copper?
The color image was generated by combining three separate images taken through WAC filters sensitive to light in different wavelengths; filters that
transmit light with wavelengths of 1000, 700, and 430 nanometers (infrared, far red, and violet, respectively) were placed in the red, green, and blue
channels, respectively, to create this image. The human eye is sensitive across only the wavelength range 400 to 700 nanometers. Creating a
false-color image in this way accentuates color differences on Mercury's surface that cannot be seen in the single-filter, black-and-white image
released last week.
