For Rainbow 24
I've been collecting my rainbow images for a while. I can't believe that I've almost got enough of each colour to fill my calendar.
It takes the pressure off from my main album which I'm still managing to keep up with photos taken every day.
@robz To me this is blue. I consider indigo to be anywhere between a dark denim blue and bluey purple. I tend to pick something in that range and try to keep to a similar shade for all of my indigo shots for the month. It often means tweaking the colours.
