Ребята помогите пожалуйста найти загадки на английском языке. Кто знаток английского плиз. Help me!

Clean, but not water,
White, but not snow,
Sweet, but not ice-cream,
What is it?

I am purple, yellow, red, and green
The King cannot reach me and neither can the Queen.
I show my colours after the rain
And only when the sun comes out again.

What occurs once in a minute, twice in a moment and never in a thousand years?

The more you have of it, the less you see. What is it?
