Outside of the Christmas and Easter Seasons (including the preparatory Advent and Easter) we celebrate the Paschal Mystery on Sundays called "Ordinary Time". You see that we identify each Sunday as something like 2nd Sunday in Ordinary time, 9th Sunday in Ordinary Time, 36th Sunday in Ordinary Time, etc.

Most people interpret the word Ordinary as "plain" or "common". But in the context of the Sunday Mass, the term Ordinary means "numbered", hence 2nd, 3rd, 9th, 36th Sundays in Ordinary Time. The liturgical color for Ordinary Time is green, the color of life and nature.
 

Each Sunday is a celebration of the Resurrection, therefore each Sunday is a mini-Easter and there is certainly nothing plain or common about that... unless you consider Easter and Christmas as being "extraordinary", which they truly are!
