Every so often a moment of sunshine interrupts October's perpetual rain:
Which got me wondering: what would happen if I took a closer look at a photographed rainbow? I tend not to pay them much attention as a colour subject - they seem something of a cliche, shorthand for "stripes of everything".
Try as I might, I could only find very desaturated hues. Perhaps the eye interprets a brilliance that isn't technically present? So I boosted the colour saturation with the photoeditor:
Interesting - the cool end of the spectrum comes up vividly, but the warm hues remain muted. Look at the palette all together, though:
It is almost an exact replica of the heathery hues in my stash of Jamieson & Smith 2 ply. I'm quite sure this is not a coincidence. I wonder if tropical rainbows are more intense, or perhaps it is simply the brilliance of the light and the surrounding flora that inspires the saturated colour sensibility of sunnier climes.
