The ocean looks blue because the water absorbs some colors and reflects others, just like how your favorite shirt might look different under a lamp than in sunlight.
Imagine you're playing with a bucket of colored candies. You dump them all out, and the red ones get eaten first, but the blue ones stay. That’s kind of what happens in the ocean: the water takes in some colors and lets others shine through, blue is the one that wins!
How Light Works Like a Playful Game
When sunlight hits the ocean, it's like shining a flashlight into a pool of colored blocks. The light travels down, and as it goes deeper, the water eats up most of the other colors, red, yellow, and green, but the blue keeps going, bouncing back to your eyes.
So when you look at the ocean from above, you see that blue color, it's like the water is wearing a blue shirt!
Sometimes the ocean can look green or even black, especially in deep parts where not much light reaches. But most of the time, it’s just having fun with blue!
