Gray Paint

I went to paint today
and my only brush was gray

I painted red today
The color of blood and blazing skies
but my only brush was gray

I painted green today
The color of life and broken bile
but my only brush was gray

I painted blue today
the color of water, air and tired souls
but my only brush with gray

I painted black today
the color of shadows deep and deciding lines
but my only brush was are gray
