Looking for a Right Paint Color

Since we are planning to removed all the popcorn in the ceiling with the house that we recently bought. We went to Frazee paint to check out some color. We don't want any overwhelming or too dark color in the ceiling of course. So we decided if we wanted the shell white or the shadow white for the ceiling. We compare both of these color and decided to have the shadow white. We don't like the Shell White much because it is more darker than the shadow white.
