's always been my view that God invented color in all its vividness, intensity, vibrancy...and to wear bright colors is to honor God.
God could have made things in black and white...or green, yellow and red...but he chose a whole range of color to express himself and ... just for pleasure! How beautifully colored things are - that we cannot see - the workings inside animals and humans - fish at the very bottom of the sea - plants that have colors the human eye cannot see...but bees can. What playfulness!! What variety!!
Always amazes me that churchmen dress traditionally in long BLACK robes. Black the color of darkness.
All the best with your book, Spec.
