Thank you so much for your thoughts and comment @rhethypo, this is very very interesting for me. When I started to work with colors I noticed how much "color energy - system - influence" in diverse systems there is in almost every culture of the world.

This is a chakra color chart found at grippz.com - as you can see the "hierarchy" used in many systems, also magical or alchemistical or "others" is always like "highest" level white or indigo and bottom level red.

This is very interesting indeed, there are also "hierarchy" systems where according to this "ranking" gems associated with the colors are used. Some even corrupted this gift of nature for own purposes and goals, e.g. not only in marketing and sales. Unfortunately, every most precious gift can be turned into something to influence the people ... ughhhhh.
