Indigo

Indigo is a fairly rubbish colour, and only really owes its prominence in our culture to Isaac Newton's desire for symmetry in nature. He believed the spectrum should have 7 colours, just as there were 7 notes in the musical scale, 7 planets (in his time) and 7 days of the week. So he shoved an extra one in between blue and purple.

So my non-belief in indigo is reflected in the blip. I could actually have easily found indigo - the chairs in our office, mucked about with a flourescent lamp, even my jeans. But here's something oblique.

Edit: just realised this is this camera's birthday: 365 days and still blipping strong (well, haven't blipped every intervening day and even then, a couple of the blips were from the phone's camera!).
