The Field reads color the way a painter does — the palette and each color's job, and whether that color rides the structure of the picture or floats free of it. In plain language, in your browser.

The color-field readout above is computed locally and is deterministic. Deep Read sends the image plus the readout to Claude for a written one-on-one color critique — the painter's voice on top of the instrument's numbers.

Most color tools pull a palette and stop. The Field asks the harder question — what is each color for, and is the color built into the picture or laid over it? It comes from the Visual Thinking Lens (VTL) color kernel, working in OKLab so lightness, chroma, and hue are measured the way the eye weighs them.
A deterministic five-color OKLab palette, each swatch assigned a compositional job — ground, light, shadow, structure, accent — with its lightness, chroma, and share of the field.
The kernel measures the high-chroma mass against the structural mass: do they stack, or separate? The Coupling Index says whether color is doing structural work or floating as an independent layer.
The numbers become paragraphs: what the palette is, what its loudest color is doing, whether the value or the hue is carrying the picture, and two or three concrete things to try.
The same instrument serves two audiences: people who make images, and people who make image-makers.
The half of a studio review that's hardest to get: not "nice colors," but whether your color is structural or decorative, where your accent is actually sending the eye, and whether value or hue is doing the work.
Generators don't just settle compositionally — they settle chromatically: narrow hue fields, one dominant palette cluster, color that floats decoratively over form. The Field measures palette compression, hue breadth, and color-structure coupling across an output corpus.
