Change color of red cluster which comes up if size of cluster is between 100-1000

[KunalGadhia]

Issue description
Library is the best to create marker clusters on the map but based on feedback shared by few of our end users I thought that I should convey the same to you. Their feedback was that when the cluster has between 100-1000 markers inside the cluster the color of cluster becomes red. In general scenario the red color depicts the color of warning or danger, so was wondering if we could change the color of that cluster icon to orange/saffron instead of red it will be more appropriate.

Steps to reproduce and a minimal demo of the problem
Wherever we have more than 100 markers in close proximity and then when we try to zoom out the cluster is formed and if the markers inside that cluster is between 100 to 1000 the cluster color is red.

Current behavior
Wherever we have more than 100 markers in close proximity and then when we try to zoom out the cluster is formed and if the markers inside that cluster is between 100 to 1000 the cluster color is red.

Expected/desired behavior
Since red cluster color depicts danger or warning, the color of that cluster should be changed to dark orange/saffron or any other color except red.
