Hapless poetry 3

Seven shades of gray,
The third a blue,
The first a white;
A serried transgression
Aflutter--

A tree alone among the gallows
Bathed in the grays
Of violets and reds,
A candid antinomy
Aflush, resigned--

Seven days and seven nights,
Alone behind cold blue skies
And pale-dark nights--

A pallid refrain
Treaded on treaded line-
When grays on powdered gray
Despise the color they override.
