How to choose the right concept and color combination for a logo?

Question

Design

Hello! I faced such a problem: I came up with a logo for the radio station "Musical Wave" for music of various genres (rock, classical, jazz, etc.), but I was advised to focus on some 1 priority direction. In the course of deliberation, the genre of rock music disappeared by itself due to the ornate logo, so I decided to stick with the classics. But another problem arose: how to come up with a color combination so that it would not be frequently used and uniqueness could be traced. The proposed range of sepia does not suit me, I want something more strict and at the same time concisely light. I was thinking about the classic b/w, but everything has already been invented before us (the same Mezzo) ... Or is it still to think on a larger scale? For example, not a radio station, but an Internet portal for radio (like NasheTV)?
