An odd word to find an image for when you start thinking about it. Strength is a noun but not in the way soap or sausage is. Do you know what I mean.
As I have no rippling muscles to show you I have gone instead for strength of colour.
Stone, sky and parasol
Taken a few years ago near Toulouse, the sunlight was strong and bright and I liked the strength of colour thanks to the Summer sunhine.

Take a look at her lovely blog to see what other participants have thought of to demonstrate the word ‘strength’.
