God very intelligently designed this Earth. If you know anything about additive (light) color mixing, then you know the real primary colors are Red, Green, and Blue. When adding the colors of light they mix to create a brighter color. Red + Green = Yellow , Green + Blue = Cyan (teal) , Red + Blue = Magenta AND, Red + Green + Blue = White! This is actually how our computer monitors make all these colors! Here is a link for you to mess around with! http://contrapunctus.net/rgb-demo/ Notice the three primary colors in nature! You have the distant and dreamy Blue skies, the lush and nurturing Green of nature, and the deep Red of the life that flows within all living creatures. Leviticus 17:11 For the LIFE of the flesh is in the BLOOD, and I have given it for you on the altar to make atonement for your souls, for it is the blood that makes atonement by the life. So its clear from nature that God designed us to be RED. Here is another interesting connection, in Hebrew the word for Red is Adom, almost like Adam! In fact, Adam in Hebrew not only means man himself, but it also means "To be Red". How awesome is that! Let's not forget the most important connection to the color Red, the Blood of our Lord and Savior Jesus Christ! It is by having his Blood in us that we have NEW LIFE, because our old lives are corrupted by sin! John 6:53 So Jesus said to them, “Truly, truly, I say to you, unless you eat the flesh of the Son of Man and DRINK HIS BLOOD, you have no LIFE in you." I think it was God who ordained that our identity should be in the color Red, at least to some extent! That is why Red is the best color for us! God made our eyes with more Red cones than Green and Blue combined! He wants us to notice this lovely color! The color of Love, Sacrifice, and LIFE!
