Colormap: "Isolum" optimized for print & color vision deficiency (Scripts) Publisher's description
All colors have nearly the same luminescence (ideal for lifetime images that will be displayed with an additional transparency map to "mask" places where the lifetime is not well defined)
1) All colors have nearly the same luminescence (ideal for lifetime images that will be displayed with an additional transparency map to "mask" places where the lifetime is not well defined)
2) Color vision deficient persons can only see reduced color: as much as 10% of adult male persons have a red-green defiency (either Deuteranope or Protanope) -> as a result they can only distinguish between blue and yellow. A colormap which is "save" for color vision deficient persons is hence only based on these colors. However: people with normal vision DO have a larger space of colors available: it would be a pity to discard this freedom. So the goal must be a colormap that is both using as many colors as possible for normal-sighted people as well as a colormap that will "look" purely blue-yellow to people with colorblindness without transitions that falsify the information by including a non-distinct transitions (as is the case for many colormaps based on the whole spectrum (ex. rainbow or jet).
That's what this colormap here tries to achieve!
3) In order to be save for publications, the colormap uses colors that are only from the CMYK colorspace (or at least not too far)
4) The map is designed in order to be overlaid with an additional black/white channel (ex. for adding an additional phase-contrast image. However it should be noted that for colorblind people: since blue&yellow are complementary colors there always is a transition in this colormap over gray. This part is difficult to be optimized for colorblind-persons.
5) There exist also the more rare form of blue-yellow colorblindness (Tritanomaly). However it is almost impossible to design a colormap that employs as many colors as possible and is save to be viewed with ALL color deficiencies. Since this more rare form affects only 0.2% of people, I have optimized it for the more common form of red-green deficiencies only.
