Question

Crayons are imaginations,
Always creating something new.
They scribble and draw
With so many colors,
Too many to choose.
The sky doesn’t have to be blue.

Crayons are creativity,
Making whatever you want.
It doesn’t have to be realistic,
The grass doesn’t have to be green.

Crayons are bright and colorful,
Or they can be light and soft.
Their just thick sticks of wax,

Answer 1

Use "They're" (not "Their").

Finish your pattern with whatever color you'd like:

yellow
orange
red
purple

Answer 2

We have no choice but to face the facts

colors are creations of our imagination

so there for we will never know the colors max

hope this helps ^-^
