I found yesterday’s rainbow\u00a0picture<\/a>\u00a0to be so delicious that it had\u00a0to be savoured\u00a0alone: it was the nicest shot I have managed of a semicircular bow replete with\u00a0its reflection in the calm waters of the Lake.\u00a0<\/p>\n

Yet,\u00a0during the half-hour I watched the rainbow, features shifted\u00a0as the shower moved along\u00a0the Lake and the lighting changed. There was much to see.\u00a0<\/p>\n

The colours of the rainbow blend continuously one into another. The crayon-box\u00a0claim that there are seven colours in the bow is silly: the standard\u00a0mnemonic, Roy G. Biv (red, orange, yellow, green, indigo, violet) merely gives the order of colours that may or may not be seen, but\u00a0which\u00a0are certainly not discrete. Other striking features seen here are that red is on the outside of the curve (not on the inside as much commercial art suggests), and it is brighter inside the bow than outside.

There is a much\u00a0to discover\u00a0in the next\u00a0scene: bright central disk, anticrepuscular rays forming radii to the bow, a larger secondary bow with red on the inside, faint supernumerary bows on the inside of the primary bow, and\u00a0colours improving\u00a0as\u00a0the bow becomes nearly vertical. A particular feature might not be evident in every rainbow, but as one watches the bow\u00a0evolve, each is worth descrying. The fact that these characteristics are well understood only enhances the grandeur of the event.
