I've replaced each color

Red smells of sulfer
a luring chill, howling sirens, silk mist clung to wet skin
YOU ARE MINE, OBJECT
  clouds cover sheep wool, that chars in heat

Yellow cracks pepper over itself
impact pops gemstones, vacant kings crown
Horses clomp toward them
MY CROWN! STOP YOU'LL CRUSH IT!
  pill bottles shake above burning cities

Blue of baby powder
budding from pollen, crying children
droplettes falling into a body of water silently
open mouths, dancing wet tongues,
WHY CAN'T I HEAR BLUE SCREAMING?
  I can't hear blue screaming

BLUE IS SCREAMING!
NOBODY CAN HEAR BLUE SCREAMING?
  color are uncomfortable
