What do the four colors of the tabernacle represent?
The four colors used in the tabernacle gate are blue, purple, red, and white. Blue represents Christ's heavenly origin, purple His royalty, red His sacrifice, and white His righteousness and holiness. These colors appear throughout the tabernacle and all depict Christ.
Les explains that the gate curtain of the tabernacle was made of fine linen but not white; it was comprised of the four colors that appear throughout the tabernacle, all depicting Christ. Blue speaks of His heavenly origin, purple of His royalty, red of His sacrifice, and white of His righteousness and holiness. The gate itself represents Christ, the door to the sheepfold. The outer white linen fence, by contrast, depicted the righteousness of Christ and God and kept the common person from looking in on the things of God.
