Although rare, total colour blindness exists. But also for daily use with unlimited colour vision, scientific papers are often printed in black&white (i.e., grey scale), which normally causes figures to become unreadable. Making black&white readability an integral property of colour maps, importantly contributes to the inclusion of colour blind people, the wider accessibility of the visualised data and, on top of that, saves colour ink, money and, if only to a little part, the environment.
All Scientific Colour Maps are readable in black & white.
