This Project used only black and white to represent the colours of Red, Yellow, and Blue. On the left side of the image below, Yellow is represented. The middle construction is  Blue, and on the right ride is Red. Red here represents fire, and as fire is large and complex,  the amount of the Red is greater than the other two colours. Here, Blue represents water. The colour is calm so only a small amount of squares are used. Yellow is between Red and Blue, and while Yellow is a little calmer, it's not cooler than Blue, nor as busy nor large as Red's representation as fire.
