Cubehelix does deserve a mention if only for being the first to bring this idea to the "mainstream", but for the record: this is also true for Inferno, Viridis, Cividis, etc.

I wosh cube-helix had more saturated colors. It might be good for vizualizing, but it doesn't pop.

There are a few parameters you can adjust to get brighter colors. A nice online implementation is at >> http://www.mrao.cam.ac.uk/~dag/CUBEHELIX/cubetry.html

adjusting the hue parameter up to 1.4 will give more saturated colors
