Secrets of the Color Coding in a Catholic Mass

         The term "color coding" is not the right term to describe the colors that are being used in a sacred mass. These colors are called Liturgical Colors. These colors are important for us to know what is the Liturgical season we are celebrating every mass or everyday.
         Liturgical Colors are those specific colors which are being used for vestments, altar coverings to denote special times in the Church. The symbolism of colors may serve to underline moods appropriate to a season of the liturgical year or may highlight a special occasion.
         These are the Liturgical Colors that are being used:

WHITE 

LIGHT, INNOCENCE, PURITY, JOY, TRIUMPH, GLORY

> Season of Christmas
> Season of Easter
> Feasts of the Lord, other than of His passion
> Feasts of Mary, the angels, and saints who are not
    martyrs
> All Saints (1 November)
> Feasts of the Apostles
> Nuptial Masses
> Masses for the dead (Requiem Masses) when
   the deceased is a baptized child who died before the
   age of reason.
                  
 Note: White is the color of Popes' non-liturgical dress. White can be replaced by Silver
