Blueberries - indigo berries?

Day 6 of the 7 day rainbow challenge I have with Cath.

Ok so it's another food photo -easy subject matter but I was struggling with indigo!

Blueberries. Well, they're not blue. However, I much prefer bilberries to be honest, but they're wild foods not commercially farmed to the same extent, so I understand.

So this is my Blueberries with Greek yogurt and Oats (not visible) - another tasty snack as part of my healthy eating regime.

Time to eat!
