You need to post pictures and IMO a color palette starts with the choice of bedding and bed so show us that. My fave is a gray bedroom but I need to see yours. From your idea books it looks like you like saturated color which IMO are too much for a space that should be restful but I need more info.

It’s really a personal decision based on taste, as well as other important considerations (natural light, flooring, accessories, furniture, etc.). Deciding on a color scheme is only the first step; you then have to think about undertones, etc. There is a lot of helpful on line information in this regard.

If you are only curious about what people prefer, the vote will be fun, but if you want more specific help, providing a picture of your room and giving more details (will you be replacing anything, colors you are drawn to, etc) you’ll get more useful information
