Unfortunately, scientific data is still often presented using rainbow-like colormaps. People are used to them and appreciate their visual appeal. Despite their aesthetic appeal, however, these colormaps have some well-known limitations.
- They are not perceptually uniform. Using them is essentially the same as drawing linearly increasing ticks with irregular spacing on an axis. Consequently, a perfect linear function would appear as a non-linear curve.
- They are also not suited to colour-blind people.
- They also become ambiguous when converted to greyscale.
Therefore, I propose to use a perceptionally uniform color map instead as default. Grid look already supports various of them, so this should be possible without a lot of effort.
Thanks for developing this nice tool!
