I agree with you @Jo_SQSP, using a color that stand out is the best way to go most of the time.
I've done quite a few reviews on peoples websites here on the forum, and one thing that I see many websites do wrong is not using colors that resonates with what they want to communicate.
For example:
I want to be personal - use a warm/soft color like low-saturated beige or brown
I want to show authority - use blue or black
I want to stick out - use a distinct color like yellow or pink
