Interpretation of colors with multiple density maps together

[ChristianMichelsen]

Hi all,

I was wondering how to interpret the colors when one is plotting multiple density maps together, does anyone know this? Say e.g. the example in the README:

How does one interpret the color in the middle? Is it possible to quantify the color by a color scale?
For example, if there are three blue dots in a pixel and two reds, does that make a purple pixel?

Thanks a lot!

Cheers,
