Hsia Yu, Pink Noise (粉紅色噪音)

What it is, and who made it

Pink Noise is a book of poems by the Taiwanese poet Hsia Yu (夏宇).

• Edition (from memory, moderate confidence): 2007, self-published, printed on transparent plastic sheets rather than paper.
• How the poems were made (same confidence): English text found online was passed through translation software into Chinese, and both versions were printed.
• What the saved images confirm:
  • the slipcase text names "Sherlock" and "the English";
  • the title lockup reads PINK NOISE / 粉紅色噪音 / Hsia Yü 夏宇.

The photographs were shared by @longtheriverrun, quoting @janjirasun. The photographers are not named, so credit them as unknown. @janjirasun's words: "the semi-transparent page layered on top of something super opaque, adds another layer of context to whatever is underneath". @longtheriverrun's words: "the densely set, heavy 明朝 type ... instills such a noisy, interferential affect".

Parts, layer by layer

Read it from the light inward.

Type as a layer.

• The Mincho face: thick verticals, hairline horizontals, triangular stroke ends (uroko). Set heavy, its counters close up where lines overlap (O).
• Density: in image 4 the row profile finds 26 dark-mark rows at a pitch of 0.0117 of the frame height (M).
• Two inks (black, magenta) over two scripts (Latin, Han). The ink may encode which sheet, or which translation pass, a line belongs to. That reading is inferred and not confirmed.

How the layers interact.

• Occlusion: a glyph hides what lies behind it, and clear film between glyphs hides nothing.
• Blur grows with distance: print touching a frosted face stays sharp; print a few millimetres behind it turns to colour fields (I, from the optics of a diffuser).
  • The magenta measured through frost (#a6677e) against magenta on clear film (#ab6087) keeps its hue and loses value and edge. That comparison is weak, because it crosses two photographs.
• Interference: dense Mincho rows are line grids. Where the loose sheet crosses the cover block at about 20 degrees (image 2, O), two grids beat against each other. That is the "interferential affect" the sharer names.
• Reading order follows depth: the sharp top sheet reads first, and deeper sheets read as murmur (I).

The concept. Translation becomes physical layering, and the gap between two languages becomes a measurable depth. The title names the signal model: pink noise is 1/f, with equal energy per octave. Every scale carries the same weight, so no single sheet dominates the reading (I).

The framework behind it

A page is a stack of filters, and reading is a ray through the stack. Each layer has two parts:

• a material: clear, frosted or opaque; its scatter radius; its tint;
• a mark set: glyphs in one script and one ink.

What the eye sees at a point is the composite along the ray. A mark at depth d behind a diffuser is blurred by a kernel that grows with d.

Three parameters do most of the work:

• the gap between sheets;
• the scatter of each face;
• the density of each sheet's line grid.

Meaning is assigned by depth: sharp is "said", blurred is "underneath", and crossing grids is "noise". The book is a hand-made instance of the compositing model behind every renderer: an over operator with a depth-dependent blur.

The same idea in distant fields

• Cartography and anatomy: overlays and acetate atlases. Classic anatomy books layer skin, muscle and bone on clear sheets. The reader peels a body the way this book peels a translation.
• Palimpsests: medieval parchment scraped and rewritten. Multispectral imaging recovers the under-text, which is depth recovery by another physics.
• Audio: stacked takes, reverb as distance, and the noise floor. A quiet layer under a loud one is heard as texture before it is heard as words. Pink noise is the reference test signal.
• Signal processing: frosted glass is a low-pass filter whose cutoff falls with distance.
• Shoji screens and frosted bathroom glass: privacy by scatter, where presence shows but identity does not.
• Version control: a diff view is two layers of text, one struck through and one added, read together.
• Our own canon: "a witness you can see through who still changes the picture" (feed set 27 reading of glass).

Dual edge

• For readers, the device can hide. Layering exposes translation's distortions, and the same stack can bury the source under the gloss so readers trust the sharp top sheet. A Daylight-style surface that layers "what was said" over "what was claimed" must keep the source sheet reachable and labelled. Depth must never decide credibility.
• It is also a legibility cost. Dense, interfering type is beautiful and hard to read: hard for low vision, hard for dyslexic readers, and impossible for screen readers if rendered as an image. Any site use needs a plain text layer that assistive technology reads, consistent with the author's 2026-10-25 point about tools for neurodivergent people.
• Machine translation as material can launder. Text run through a model reads as authored. If we use the method, the provenance of each sheet (source, model, date) belongs in the data, not on the page.
