I spatially downscaled a night-time lights (NTL) satellite imagery using 4 different approaches. When I submitted my results to a journal, one the of the comments I got from a reviewer was, and I quote: 'the results in Figs. 3 can be presented in color to display the difference more obviously.'
I would like to ask for recommendations about a color palette suitable for such purpose, i.e., to display the differences in the spatial pattern of NTL created by the various downscaling methods.
Below, is the original map I created.
