One variable. The entire visible spectrum.
Move the slider. The color you see is the film telling you how thick it is.
Below is a single specimen under fixed illumination. You are changing one thing: the thickness of a transparent thin film, measured in nanometers. Nothing else is touched. No dye is added, no pigment is mixed.
Five states the film settles into.
Each preset is a named thickness. The sample cross-dissolves between them.
Every state ships with its numbers.
A color you cannot specify is a color you cannot order. Each regime exposes a spec sheet: peak reflected wavelength and its angular drift, CIE 1931 gamut coordinates with measured tolerance, and a substrate-compatibility table covering silicon, anodized aluminum, soda-lime glass, and PET.
Sheets are issued against the specimen ID shown on the instrument, so the document and the sample on your bench reference the same deposition run.
