50 shades of blue

I had my toe nails re-done at the weekend. I wanted to have the same colour as last time, it being my favourite colour and all. The friend I went with said that was simply too boring, and tried to persuade me to have bright red. I didn't fancy that idea, so I relented slightly and decided on a slight variation on the spectrum of my favourite shades of blue. They have many more on the same chromatic theme - I wonder how many I will get through before I leave!
