Why is the sea blue from far away?

Stand on a beach and look out at the ocean. Why does all that water look so beautifully, impossibly blue? After all, if you scoop up a glass of seawater, it's perfectly clear. So where does the blue come from?
The secret lives in sunlight itself. White sunlight isn't actually white — it's a hidden rainbow, a mixture of every color traveling together. Red light, orange, yellow, green, blue, violet, all racing from the sun at once.
