Issue(s) with release 2.2.1 (e.g: custom color doesn't work)

Hi,

custom color

While I am testing NGL 2.2.1 for nglview (nglviewer/nglview#1086) , I find that the custom color doesn't work anymore

Thanks for reporting this. I've noticed the same issue in a separate branch and did not realize it was still in production.

Thanks @ppillot. I look forward for the fix.

@ppillot I confirm the fix does work. Thank you so much, Paul.
