One definite advantage to colors, however, is expressing certain thresholds (as in the coast-line example). The only way to express multiple thresholds in gray-scale is to distort the scale, and then you no longer have a faithful representation either.
- TrevorJ 17y agoYou would still have to distort it unless you encoded the height to the luminance channel and only used the color channel to define boundaries.
- pixcavator 17y agoIf you are doing this visualization for yourself, you can experiment with colors and thresholds to bring out the features that are important (in your view). And that’s OK because you still have all the data at hand. If however this visualization is for someone else, such as the MRI given to a doctor, anything but a faithful representation would be very dangerous. Basically, you would substitute your judgment for that of a specialist.
