What is yellow?

Reflectors are yellow,

Shining back when lights shine at them,

Warning cars if you are there at night.

What is gold?

The sand is gold,

Tickling your bare feet,

Covering up all your toes.

What is black?

The night sky is black,

Very very dark and lovely to look at,

Making the stars stand out.

What is red?

A rose is red,

Beautiful and sweet perfumed,

Making your garden sparkle happily.
