At the local nursery school, I was chatting to my daughter's friends and noticed a number of things.
Frankie has mousy coloured hair and the girl with black hair was wearing a green t-shirt.
Lucy is not blonde and Lauren does not have brown hair, Chloe was wearing a blue t-shirt.
The blonde girl was not wearing red and Lauren was not wearing green.
I can't remember who was wearing a yellow t-shirt.
Can you work out the colours of the t-shirt and hair for each child?
