Here you have to match the objects on left with their original colors on the right. So the solution, from left to right, will go like this:
Sun=Yellow
Waves=Blue
Tree=green
Then next row:
Heart=Red
Coins=Gold
Nut=Brown
Then last row:
Road=Black
Snowflake=White
Fire=Orange
Once you solve the puzzle, a glowing key will appear. Use it to escape this level.
