I'm not a huge fan of blue (even though I couldn't imagine life without blue jeans), but a hint of blue is ok, especially in a hot summer day like this (+36C = 96F) it gives a cooling effect.
My nails in frosty blue added with some sparkles and my newest pair of sunglasses.
My small ear studs with blue crystals.
And of course, Fazer Blue, my favorite chocolate!
(Not a single piece left, ate it already some time ago...)
