I adapted a ppt on here (thanks to original contributor) to include a review about colors and a "Color Challenge" game. In this game, the students must see if the word and the color of the word match. If they do, then they should read the word. If the color of the word and the word itself do not match, they should not say the word. I'm going to use it to day and see how it goes. I got the idea from a mini-game app.
Great game!
I played it like hotseat, with a student representing each team. They'd both face the TV. If the colour and the word matched, the first student to read the sentence got a point for their team. If the word and colour doesn't match, the first student to sit down gets a point. You could be creative by changing the sit down to any other action, i.e jump, smile etc.
