If you choose a fabric that has many colors in it and you LOVE... I mean really LOVE the fabric... choose color/prints to go with that fabric that you can find within it. Also... most fabric companies place a register along one of the selvages that shows little tiny swatches of every color that is in the fabric. I find these very helpful if I am stumped about one more color I need to add. Beyond that... if YOU like your choices... they are RIGHT.... no one else matters. YOU are the ARTIST.
