Measure
Read the standard from your spectrophotometer or import a JSON file with a predefined structure. The curve always travels complete: Lab values and illuminants are recalculated, never transcribed.
The textile chemist, digitised
From spectral curve to starting recipe.
ArteTintoria.AI works alongside dyehouses and finishers with the judgement of a master colourist: it reads the measurement from your spectrophotometer and proposes the first recipe to try in the lab, before going into production.
Illustrative example: curves and values are calculated live in your browser.

How it works
Three steps, from measurement to lab dip.
02
Brief
You enter substrate, fibre fineness, material form, specification, required ΔE and metamerism check: the same information a chemist would ask for before touching a dye.
03
Recipe and reasoning
You get the starting recipe with dyes by Colour Index, percentages on weight of fibre and the reason behind the choice: what to watch out for and what to check on the first lab dip.

The master colourist’s judgement, codified.
We don’t clone a colour matching system. We digitise the technical commentary an experienced colourist makes on every single case.
Metamerism comes first
When two candidates match equally under the primary illuminant, we pick the one that “shifts” least when the light changes. Cost comes second.
Colour Index, always
Every dye has two identities: your supplier’s product and its universal C.I. We reason by C.I. and execute by product.
Numbers before opinions
ΔL, Δa, Δb and ΔE under all three illuminants, plus the K/S difference by band: the same figure can be a strength problem or a shade problem, and the corrections are opposite.
Every case teaches
Article and colour become a case that accumulates dips, corrections and judgements over time. More history, better recipes.
The lab traffic light
When a dip is ready to approve.
Typical ΔE CMC (2:1) thresholds. Your customer’s specification may require different ones: you set them for each case.
