Hi Plantsurfer I agree that paper from The Plant Cell has useful utilization of coloring it helps to calculate area and perimeter of cells I have one paper published with similar coloring Nature rather disappointed me no justification for coloring image Yamada did not used pseudo colors he just combined optical and SEM images  Anaglyphs are still monochrome images  one red and one cyan And we do not discuss Xray data presentation The last paper from Micron is rather childish it is the Micron way to publish such a nonsense By the way I like coloring SEM pictures So colored images can look nice but they should be avoided in publications
