Painting an Accent Wall with Multiple Colors?

I planned to paint an accent wall of my family room with random stripes (four different colors). I brought the paint and now I feel so lazy and it seems like lots of hard work. The paint is non refundable so please can anyone suggest how else can I make a pattern or how else can I work with multiple colors on a wall. The colors include light beige, light yellow, light green, and light grey on an off white wall
