green

Green referent

Record whether green identifies an appearance, a target colour or a pigment described by colour, and link any carrier separately.

1. Does green here denote an observed colour, an intended colour or a pigment sample? definition
2. What object, light, image or material carries the green, and is that carrier identified independently? boundary

Green naming basis

Keep the green label attached to its language, naming system, reference examples and unresolved boundary judgements.

1. Which observer community or colour naming system classifies this appearance as green? provenance
2. What reference or test distinguishes this green from yellow-green, cyan, blue or a nearly neutral colour? boundary

Green appearance profile

Record hue direction, lightness or brightness, and chroma or saturation using an appropriate named method.

1. How light or dark, vivid or muted, and yellow-leaning or blue-leaning is the green under the chosen method? measurement
2. Under what illumination, surround and observer conditions was that appearance assessed? provenance

Qualified green values

Attach measurement conditions and encoding metadata to colour values; keep spectral evidence when the decision requires it.

1. Which colour space, reference white, observer specification and measurement geometry qualify the reported green values? measurement
2. Is a spectral measurement needed to evaluate this green across different illuminants, and what evidence is available? action

Applied green sample

Link pigment or mixture identity to a documented sample with binder, substrate, concentration and thickness where relevant.

1. Which identified pigment or mixture produced this green, and what record supports that identification? provenance
2. What binder, substrate, concentration and applied thickness define the sample whose green is being judged? measurement

Green retention

Compare a material's green against a recorded baseline and separate measured change from proposed causes.

1. Has the green changed after drying, curing, weathering or another documented exposure relative to its baseline? measurement
2. What evidence supports accepting, retesting or replacing the material when its green appearance changes? action

Green reproduction acceptance

Record the reference green, output medium, achievable result and the method used to accept or reject the match.

1. Which physical sample or qualified digital specification is the authoritative target green? provenance
2. What visual assessment or colour-difference method and tolerance determine whether the reproduced green is acceptable? measurement
3. If the target green cannot be reproduced in the chosen medium, which substitution is permitted and who defines that permission? action

Green signal legibility

Link a green signal to its local meaning and assess its visibility alongside the actual competing colours and supporting cues.

1. What does green mean in this application, and where is that convention defined? definition
2. Can intended users distinguish this green from the background and competing signals under expected viewing conditions? measurement
3. What text, shape or other cue should accompany green when colour alone does not reliably communicate the intended distinction? action
