Read the following statement then answer the question that follows.
“My Cousin is 15 and he lives in Basra. I don't see him very often, but we often talk on the phone and we email and send messages every week. He's a good friend. Next week, we're going to see him and my aunt and uncle because it's his birthday.
I bought him a new computer game to play on his laptop. He likes games about space and games where you can build things. My parents bought him some brown leather boots and a green and blue cotton T-shirt. I wrapped them up in blue paper with red dots.”
What’s the colour of the T-shirt that the parents bought for the cousin?
