I'm doing an English poem on colors and I chose pink and yellow. what are some metaphors of the color pink and yellow (give at least 2) ?

Her cheeks were rosy pink flowers.

The lamp was a yellow burning sun.

For yellow:

They say that fellow is mellow,

But in truth his auras bright yellow,

He sits all day, rarely tinkers,

Always contemplating life, he's quite the thinker.

In psychology yellow represents people who have that deep thought thinking brain.

You can jazz that up I just whipped it up sitting in Walmart parking lot!

Not anything coming to me on pink. Other than usually refers to calm or women.
