I recently overheard this conversation between an Interior Designer (ID) and his Client (C):
ID: "But those are the colors you always choose and we agreed we were going for a different look and palette in your bedroom.
C: I know but I reeeaaallly love these colors (jewel tones) and I think this fabric would look great on the headboard.
ID: But that is going in a completely different direction that we agreed on, is that what you want to do?
C: Well, I love these colors and think they would look great with the color scheme in my home.
ID: Yes, that is because you have the same colors in the guest bedroom and your family room.
C: Is that so bad?
ID: Not if you want every room to look like the next one.
C: Well, maybe I can take the fabric home and see how it will look in the bedroom."
In the end they did not check out the fabric that she was drawn to. I don't think that was the right call. On the one hand, she had presumably asked (or otherwise agreed) that they were going in a new direction with the color scheme in her bedroom. But she was obviously drawn to the colors she loves. It certainly would not hurt to look at the fabrics she liked in the context of her home to rule out more of the same colors she likes and help get comfortable with the idea of a completely different color scheme.
So, will she ultimately be happy with a new color scheme? Probably not as the new colors were ones the interior designer liked (he was proposing grays and lavenders which are on trend today). My advice on this is to make certain that you are ready for a palette change that is on trend if it is significantly different from the colors that you love. That is because colors evoke an emotional response and you won't be happy to live in a bedroom that could be in House Beautiful magazine if you aren't drawn to the colors used in the room.
