Mustard name and boundaries Establishes which colour sense is intended and how its category is delimited.
Colour referent
Separates the colour quality from the substances and organisms associated with its name.
Intended mustard sense
Record evidence that an occurrence denotes colour, including whether it describes an appearance or names a palette entry.
- Does the registry source identify mustard as a colour rather than a condiment, plant or chemical substance? definition
- Who used the name mustard for this occurrence, and in what descriptive or specification context? provenance
Neighbouring colour boundaries
Makes the distinctions from adjacent colour names explicit and attributable.
Mustard membership judgment
Record the comparisons and naming convention used to accept or reject an instance as mustard.
- Which reference examples distinguish mustard from bright yellow, ochre, gold and yellow-brown in this context? boundary
- Is membership determined by ordinary naming, an expert judgment or inclusion in a particular named palette? definition
Mustard reference and specification Anchors a chosen mustard instance to evidence that another agent can inspect and interpret.
Named mustard references
Identifies the swatch, palette entry or specimen behind a mustard designation.
Reference authority and version
Record the origin and identity of a mustard reference without promoting it to a universal definition.
- Which source or physical reference explicitly assigns the name mustard to this colour? provenance
- Does the designation apply only within a particular manufacturer range, palette edition or local convention? boundary
Mustard colour coordinates
Connects numeric specifications to the mustard reference they actually describe.
Interpretable mustard values
Record coordinates with sufficient context to distinguish encoded targets from measured appearances.
- What coordinates specify this mustard instance, and which colour space, profile or reference conditions make them interpretable? measurement
- Were these values measured from a specimen, supplied by the naming authority or derived through a conversion? provenance
Mustard appearance in context Records the conditions under which a specified instance is perceived as mustard.
Lighting and surround
Qualifies mustard judgments by illumination and adjacent colours.
Context-dependent mustard judgment
Record whether mustard membership and reference similarity persist in the intended viewing environment.
- Under which illumination and surrounding colours was this instance judged to be mustard? measurement
- Does the instance move toward an unacceptable yellow, ochre or brown appearance in any required viewing condition? boundary
Surface and medium
Separates mustard colour from the finish and medium carrying it.
Mustard carrier effects
Record surface or medium effects that alter the apparent mustard colour or complicate comparison with its reference.
- How do gloss, texture, translucency or display emission affect this mustard instance relative to its reference? measurement
- Does a perceived gold-like effect arise from colour alone or from a reflective finish that requires separate description? boundary
Mustard selection and reproduction Supports decisions about using a mustard instance and accepting its reproduction.
Mustard match acceptance
Defines success for reproducing a selected mustard target in a particular medium.
Acceptable mustard reproduction
Record the target, evaluation method and tolerance governing acceptance of a reproduced mustard colour.
- Which mustard reference and visual or measured tolerance govern acceptance in the destination medium? measurement
- If the target cannot be reproduced, which adjustment to hue, lightness or chroma is acceptable, and who decides? action
Mustard in visual use
Assesses a chosen mustard colour in its actual visual role and neighbouring palette.
Mustard role suitability
Record whether a mustard instance remains distinguishable and serves its intended role in a composition or interface.
- Does this mustard instance provide sufficient contrast against its actual background for the intended text, symbol or area? measurement
- When mustard must be distinguished from nearby yellow, orange or brown elements, what additional labels or visual cues are needed? action
Evidence and external alignment What the world already says about this thing, gathered so the model can be checked against it.
Reported evidence
Findings from the breadth pass, kept separate from the structural claims.

What it is Filled
Mustard is a conventional colour name for a subdued yellow with a brownish cast, resembling the colour of some prepared mustards.
In scope
- Uses of mustard as a colour name and category
- Boundaries between mustard and neighbouring yellows, ochres, golds and browns
- Measured or specified colour instances labelled mustard
- Appearance changes caused by illumination, background, surface and display
- Selection and reproduction of mustard in visual applications
Out of scope
- Mustard condiments, recipes and food properties
- Mustard plants, seeds and cultivation
- Pigment chemistry and coating formulation
- Sulfur mustard and other substances sharing the name
- Complete designs, objects or brands that use mustard
Why it exists Filled
Enable an agent to recognise, describe and apply mustard as a colour quality while preserving uncertainty about its boundaries and reproduction.
Distinguishing features Filled
- The name identifies an appearance quality that can be shared by unrelated materials, rather than identifying a condiment or plant.
- A candidate instance is assessed for a yellow or ochre character; the label alone does not establish a unique numeric colour.
- Comparison with bright yellow tests whether the candidate has the more subdued or brownward appearance intended by the particular mustard reference.
- Comparison with ochre, gold and yellow-brown requires an explicit reference or naming convention because their boundaries may overlap.
- A mustard label does not require metallic reflection; metallic gold appearance needs separate surface information.
What robots and AI may and may not do Filled
Must not
- Present one swatch value as the only correct mustard.
- Rely on yellow-brown colour coding alone in material that people with colour-vision deficiency must read.
- Imply a product contains mustard because it has the colour, or the reverse.
Only with a human decision
- Approving a colour match for paid production such as paint, print or textiles.
May
- Name or describe the colour, noting its range across naming conventions and media.
- Match or convert the colour between colour spaces when given a reference value.
Moral aspects Filled
- Colour names that echo foods can confuse buyers with allergies about ingredients.
Who is affected
- Buyers
- Designers and printers
- People with colour-vision deficiency
Owners Filled

Nobody owns it; colour-naming systems differ in their definition.

- Reference colour: Identified physical swatch or colour-managed digital reference, with edition or version where applicable
- Colour coordinates: Coordinates in a declared colour space, with the profile or measurement conditions needed to interpret them
- Perceptual position: Relative hue, lightness and chroma descriptions against identified yellow, ochre, gold and brown references

Capabilities and actions required Filled
- Classify a candidate colour as mustard under a stated naming convention.
- Compare mustard candidates with identified yellow, ochre, gold and brown references.
- Specify a reproducible mustard instance using a reference and declared colour conditions.
- Assess whether a reproduced mustard instance meets a stated visual or measured tolerance.
- Evaluate mustard foreground and background combinations for a particular communication task.
- Record conflicting mustard labels and retain the evidence supporting each interpretation.
Hazards and failure modes required Filled
- Low contrast against white or beige makes text in this colour hard to read.
Standards and interfaces required Filled
- CIE 15, Colorimetry, issued by the International Commission on Illumination, provides methods for specifying measured colours without defining a unique mustard colour.
Context of use required Filled
- Mustard is used as a colour description in clothing, interiors, graphic design and descriptions of physical objects.
- The name communicates a broad visual impression, so reproducible specifications require a reference sample or measured colour coordinates.

Open questions
- Does the source behind registry id vr.tr.mustard-q1169566 confirm that the intended referent is the colour?
- Which authoritative references or naming studies document the mustard category and its variation across communities?
- Which published palettes assign explicit values to mustard, and how substantially do those instances differ?
