The Colors of the Rainbow

Sir Isaac Newton in his early physics experiments decided the colors of the rainbow were Red, Orange, Yellow, Green, Blue, Indigo and Violet. Many of us remember them as ROY G BIV. Are there only seven colors? Newton believed in numerology and thought special numbers governed all natural phenomena. Seven is a very special number. There are seven days in the week, seven openings in our head, seven seas, seven continents and many other important sevens. So, of course he found exactly seven colors. In reality, the rainbow colors unite gradually into one another. Our eyes sort them into groupings. How many colors are in the rainbow? Anywhere from three to, as many as, several thousand. It depends on who is counting and what they believe is there. Funny how what we expect to see is often what we see. The color order of the rainbow, starts with red at the outer edge and moves through the colors to violet. The brightness and the width of the bands and colors may vary greatly in an instant of time while you watch a rainbow and are related to the size of the drops that form the bow. The colors at the base of a rainbow are different from those at the top. Most rainbows only contain red near the ground. It is very rare that red is seen at the top of the rainbow. The width of the bow measured from red to violet will be about four times as wide as the full moon. The rainbow's colors are like people, I have never known two to be exactly alike. To really understand the colors of the rainbow study them closely when they appear and come to your own conclusions.
