any specific colors for the logo?

It just dont have to be Black/ Gold combination

Colours like pure black, or blue / green and other colours are possible.
It just have to be good for printing also, cause this not Gold, Chrome or something.
Pure with one colour is ok, but also colour Combination.
The color should ultimately give confidence in connection with the logo, must not look cheap. Orange as an example stands for a cheap airline, so would not be optimal. since it also comes on the cosmetic and medical laser, these systems are usually white or light gray, rather no bright yellow. a darker, rich color maybe the i point as a Swiss flag? does not have to be.
