As an artist, I learned that mixing red and blue makes purple. Red mixed with yellow yields orange. Blue mixed with yellow produces green. If you mix all of the primaries, you get, well, mud. (RYB color model) This has been refined. The Subtractive Primary Colors are cyan, magenta, and yellow. They produce black at the core.
But, the ADDITIVE PRIMARY COLORS are red, blue, and green. These are used in television and LED, sources that use light. At the core, they produce white light.
God is the true light, the purest form, a spiritual light.
I’m not a scientist, but I see something cosmic, something heavenly in all this: God is light. And at the core, is pure white.
“The LORD wraps Himself in light as with a garment; He stretches out the heavens like a tent.” Psalm 104:2 NIV
“who alone has immortality, who dwells in unapproachable light, whom no one has ever seen or can see. To Him be honor and eternal dominion. Amen.” 1 Timothy 6:16
“In Your light do we see light.” Psalm 36:9
Is this not Yahshua (Jesus Christ), the Second Person of the Trinity? He is here in the Book of Daniel.
“As I looked, thrones were placed, and the Ancient of Days took his seat; his clothing was white as snow, and the hair of his head like pure wool; his throne was fiery flames; its wheels were burning fire.” Daniel 7:9
Compare this to Jesus (Yahshua) in the Book of Revelation.
“The hairs of his head were white, like white wool, like snow.” Rev 1:14
This is our Yahshua! He is pure bright light!
“Send out your light and your truth; let them lead me; let them bring me to your holy hill and to your dwelling!” Psalm 43:3
Someday, I expect to see the awesome colors in His Mount Zion, His New Jerusalem! I believe they are much more intense.
