Why are Violets Blue?

Why are violets blue?
For the red roses are too,
When color is just subjected,
A feeling deeply invested,
White, is as pure as doves,
Ascertaining to those above,
Black, as dark as crows,
Representing the most wicked foes,
Red, an emotion of love,
Your hand fitting hers like a glove,
Yellow, the joy and happiness you feel,
The feeling of this was surreal,
Orange, enthusiast and successful,
She will never be detest full,
Blue, stabile and trustworthy,
Your knowledge it'll fortify,
Green, is growth that fertilizes the land,
Done so with her loving hand,
Purple is for no pauper,
Fitting only a seigneur,
But these colors are only of a rainbow,
Just sundry meanings for what we see,
These meanings we are endowed,
But that is not the same for you or me,
A color may mean a million meanings,
You would be millions of shades of the most beautiful rainbow,
And my palette would still be wet if I painted for a million years,
For your beauty is beyond color,
Compared to no other.
