It's a very beautiful white world out there so it's a perfect canvas for some bold colours. I love the magical transparent colours in this Johnny Miller photograph. It's the graduation of colours that makes it so interesting though - from sea-green to blue.
You could have lots of flower fun by creating colour graduated displays or perhaps bridesmaids with different palettes of colour.
A magical idea for a magical white world!
