On the left, an array of

m

×

m

2

rectangles are colored red, green, or blue with probabilities weighted by three positive numbers,

r

,

g

, and

b

. The rectangle on the right is colored by mixing red, green, and blue in the proportions

r

,

g

, and

b

. As you increase

m

, the overall color of the array on the left approaches the color on the right.

(The

,

b

controls are sluggish when

m≥10

, so lower

m

before changing the color controls.)
