As to their colour, there are various views on angels. Some theologians believe they are entirely white whereas others describe them as luminous beings and as radiant images of brightness. Since they are thought to be either purely spiritual beings or spirits endowed with ethereal or airy bodies, they are often pictured as transparent and having a translucid nature. Despite their spiritual nature, angels can assume a human appearance and can have a body analogous with the human but their food obviously bears no relation to that of humankind since it is heavenly.
Angels prefer different colours according to the functions they perform:
- Guardian angels love pink and light-green.
- Healing angels prefer sapphire blue.
- Birth angels like light-blue.
- Angels of music love white.
- Nature angels love apple-green.
- Wisdom angels love yellow.
"And thou shalt make two cherubims of gold"
The brightness of cherubims denotes their fullness of knowledge and stream of wisdom and their readiness to receive the highest vision of light. The name of the seraphims means fire (saraf). In Isaiah 6, the angel of the Lord (the seraphim) cleanses by fire. Their fiery or burning nature thus corresponds not to death but to purification. Their light-like and light-shedding characteristic destroys and dispels every kind of obscure darkness.
Baby angels are always shown in white. They are said to love delicate floral fragrances and soft melodies like lullabies or those played by flutes and violins.
