Colour week is my personal favourite, and this week we are going with the colours of the rainbow.

Violet, Indigo, Blue and Green, Yellow, Orange and Red.  (I now have that song in my head) 

You can have all the colours in your photo, like my photo, or maybe just go for one colour a day, and as there are seven colours you will have a rainbow at the end of the week.  Or maybe you will just pick one of the colours and go with that for the whole week, the choice is yours.
