• Add setPackedRGB() and getPackedRGB() to Color class
• Read material colors from settings
• Support of material colors in settings

is it ideal to have a default color (actually more like a material) based on defined preferences? Why not use a default material picker in the preferences, we already have a material called "Default"?
@davesrocketshop FYI

This is a planned update. The original merge was intended as minimal viable product to find and fix issues as soon as possible. There will be a follow on that addresses this.

After having changed the specular colour of the default material to light grey (f6f8243b7e3c) we need a way to let the user customize it because in several cases the bright reflection can be very annoying:

A user has to set the material for every newly created object over and over again. IMO, this isn't very user-friendly.
