What are twinkle and change colors?

Twinkle and change colors are when lights flash on and off or show different colors, just like when you play with your favorite toys.

Imagine you have a toy that turns on and off, like a little nightlight. When it's on, you see light; when it's off, you don’t. That’s what twinkle is: the light flashes or goes on and off, making it look fun and bright.

Now imagine you have a toy that can be red, blue, or green, like a colored pencil. When you switch colors, it looks different each time. That’s what change colors is: the light shows different colors one after another, just like how your crayons change from yellow to purple.

Sometimes, lights do both, they twinkle and change colors! It's like having a toy that turns on and off and changes its color every few seconds. That makes it look even more fun and exciting!
