She sits unaware of her beauty so fair
With magenta eyes and rainbow hair
Her beauty like the sky
Watercolors prismatic, magenta eyes
Pools deep, I wish to swim there
And soar through her skies
My rainbow mare
I smile at her, she sees my love
I give her a coy smile
She gives me a playful shove
Her body lithe, strong, and true
Her cyan coat, shames the skies blue
She holds my heart, loyal, laid bare
Oh how I love
My rainbow mare
All bravado and guts, brash and strong
Tells me I'm right
Knows when I'm wrong
I hold her close, thankful she's there
Oh how I love
My rainbow mare
