What does Genesis 30:33 mean?

'In the future, if you check up on me, my honesty will be clear. Any goat that's not speckled or spotted, or any lamb that's not dark-colored, will be considered stolen.' Genesis 30:33 - Modern Text Bible

(Jacob sets up a system where it's easy to see if he's cheated—his animals will be visibly different from Laban's.)
