And he made the veil [between the Holy Place and the Most Holy Place] of blue, purple, and crimson colors, and fine linen, and embroidered cherubim on it. (2 Chronicles 3:14 AMP)
It is interesting that God wanted color facing His Most Holy Place. It's not all pure white, it's not monochrome. It has a brightness and contrast and depth to it. Then it's decorated with the cherubim that are over the Mercy Seat. Maybe that is pictures on the wall of some of His angels that are hovering near the throne in heaven.
God made the earth full of color, diamonds sparkle on the ocean, white bright sun, green, blue, purple, pink flowers, sky. Maybe He wanted us to experience a little of His heaven. It sure seems that the Tabernacle is a picture of God's heart, the place we'll dwell when we arrive home.
Fall is the fiery change of colors. They can be breathtaking. Spring and summer bring colors of their own. Our lives can be colorful also by caring for a person in need, or laughter when you're a little down, watching a sunset. There are so many ways to find color in life, literal and figurative.
Jesus came to His people at a time when there was only oppression and no color in their lives. There was a bleakness and a deep need for a Savior. He came to rescue them but it was not from political oppression. It was from their own sin and lack of color in their hearts. He brightened them by healing, by loving, by teaching. Then by taking upon Himself the cross and our sin and coming back from death He gave freedom to souls and placed a power in us to see color in every circumstance and give color to the lives of others whenever they need a view of Him.
