Color theory includes: (1) the color wheel, (2) factors in harmony, and (3) the context of how color is used. Spiritual analogies can also be drawn, as with the color white used for the great harvest in John 4:35, the Transfiguration in Matthew 17, and the white raiment of the saints and the vast innumerable multitude appearing at the Great White Throne. The garments of the innumerable multitude were washed clean in the blood of the Lamb. The white radiant garments worn by the resurrected saints symbolize the righteousness of the saints, made possible by the indwelling of the Holy Spirit.
