Try to find patterns that allow you to predict colors that will appear in rows of dots. Each row is produced from the one above it, following simple rules.

• If the two dots above are the same color, then the dot below matches both.
• If the two dots above are different colors, then the one below is different from either.

Assuming we have dots of 3 colors – e.g. blue, red, and yellow – these rules are illustrated in the attached images.
