This is how the above animation came to be:
I was listening to Jon Spencer Blues Explosion’s song “Orange” and I thought it might be nice to have all the words of the rainbow chopped together with a very simple animation of coloured circles.
I searched my music for songs with colours in the title, and didn’t really do much more.
Later in the day, I was drawing the circles and listening to the Pogues album Rum, Sodomy and the Lash. As always happens after track four, the fifth track was “A Pair of Brown Eyes.” It seemed a shame to not have brown in the rainbow animation. And it was amusing to me to think that brown would be pissed off with the rainbow colours.
I opened Wikipedia and had a look at some pages about colour and came across a page about a book called “Basic Color Terms: Their Universality and Evolution” by Brent Berlin and Paul Kay, which lead me to a page about basic colour terms, and that some of the most basic colour terms aren’t named in the rainbow colours. That sealed the deal, really.
The original idea would, it turned out, only be a title sequence for something about the colours not in the rainbow.
