Dave Bonta gives his five-line poem a title that names the one thing the poem never mentions. "Grayscale" belongs to the vocabulary of screens and photographs, where color is stripped away and only the shades between black and white remain. Yet the poem opens by naming just the extremes: "White and black." Gray is left for the reader to supply, and that gap drives the whole poem.
The second and third lines make the boldest move: "day buried night / in birch paper." We usually expect night to swallow the day, so the reversal catches us off guard. Here brightness wins, at least on the surface. The setting is just as slippery. Birch bark is pale and streaked with dark marks, and it can be written on, so "birch paper" could be a tree trunk, a page, or a black-and-white photograph. The poem never says which, and judging by the imagery it doesn't need to. In each case a pale ground carries dark traces. "Buried" is also the only verb in the poem, and it is a heavy one. Whatever is buried still exists underneath, so night is hidden rather than destroyed, and the two opposites share one surface.
Then the poem changes gear. Where the first three lines build a sentence, the last two are fragments with no verbs: "A Zen monk. / Any hat." The first of these brings in a human figure, perhaps a dark robe against a pale background, perhaps only a feeling of stillness. Zen is popularly linked with paradox and with loosening rigid either/or thinking, which sits neatly beside a poem about black and white sharing a page. Then comes "Any hat," which deflates the mood. It sounds like a shrug, or like someone ordering at a shop. The detail is generic, as if the monk's identity, and even his headwear, barely matters. That joke keeps the poem from becoming solemn, and it also supplies the missing gray: something ordinary, undecided, neither one thing nor the other. "Any" hands the choice to the reader.
The poem's sound reinforces this plainness. The lines run three, four, four, three and three syllables, and nearly every word is a single beat: white, black, day, night, birch, Zen, monk, hat. These short, hard words feel like stones set down one at a time. "Zen monk" puts two stresses side by side, so the line slows almost to a stop. "Birch paper" starts on a hard consonant and leans just as firmly. There is no rhyme scheme, but there are faint echoes. "White" and "night" share a long *i*, and "black" and "hat" share a short *a*, so the poem ends on the vowel sound with which its first line closed. The colon after "black" works like a hinge, as though the poem asks a question and answers with images. Each full stop in the last two lines cuts the poem into separate frames, like snapshots laid side by side.
What makes "Grayscale" worth reading is how much it does in so little space. It sets up a series of pairs: day and night, white and black, a spiritual figure and an everyday hat, solemnity and a joke. It refuses to settle any of them, and its real subject seems to be the territory between. Its brevity recalls haiku, with its reliance on images and its trust in the reader, though it doesn't follow the 5-7-5 pattern. It also shows how a title can do half the work, since the word "gray" appears nowhere in the poem and yet is the thing we leave thinking about. The last line goes on being playful after we've finished reading, because we still have to pick a hat of our own.
