Re the app: the color mapping option is reached by Phob->Search Mode; 
the yellow '+' button selects from ~10 color-matching algorithms to 
match the next pair of pics. Alg used is shown if you hold down mouse in 
area next to the options. ~7 of the color-match options are 
histogram-based. Other histogram-based options use the Golden Angle in 
color space to find pairs; the options are numbers indicating the number 
of dimensions of each space involved.
