Write about a color without mentioning the actual color (only shades of it) in the body of the poem

The color lingers in every corner of every house
away from the sunlight, adding shadow to the faces of toys and the curves of furniture
On the edge of the woods it lies in the grass, the opposite of the peaceful summer sun.
It creeps up at night,
like a storm, its hands slowly grasp around you
covering everything, suffocating all light.
By fires it dances in the night
with many arms and legs
slipping in and out of vision.
in the morning it walks away,
creeping over the land.
only to linger in corners and
in the grass
