Colors at full brightness

I am a rainbow you can't see.
I guess you're color blind.
You chose to look the other way,
with full of darkness.

You're the reason for my rainy days.
But with just a smile,
you bring the colors back to life.

No matter how bright I shine,
For you, the storm is all that matters.
Please see the colors in me.
Beyond the worst days and the bad times,
I will be a beautiful rainbow lighting up your day.
