Oh my! I use white often. Sometimes white is the only color to make something pop. I often use white on white, but I am looking for cotton whites that seem denser and not as see through. When appliqueing with white (or any light fabrics) I usually cut out the fabrics underneath so the colors don't show through. I use white batting when there is white in the quilt, but always off-white when I use cream fabrics - then the fabrics have a softer hue than when you use a white batting.
