Blue (Heaven)

Woven into or embroidered on the linen were blue, purple, and scarlet threads. The Hebrew word for blue means shellfish. A brilliant dye was excreted from this mollusk. This bright color is always mentioned first. Man needed something something to suggest the idea of heaven as a place from which God reveals Himself more fully than on earth. Therefore the color blue represents heaven, the color of the sky. We see the loveliness of the blue in the life of our Lord Jesus Christ who was not only heavenly in His origin but in His very nature and ways.

Jn 3:31 "He who comes from above is above all; he who is of the earth is earthly and speaks of the earth. He who comes from heaven is above all.
