Mahogany meaning Establishes what a mahogany designation means in its particular use.
Colour sense
Determines whether the observation belongs to this colour model.
Designation target
Record whether mahogany names an appearance, a material or a botanical identity, preserving ambiguity when evidence is insufficient.
- Does mahogany describe how the subject looks, what it is made from or which tree it is? definition
- What registry source or usage example supports treating this entry as a colour quality? provenance
Named colour boundaries
Locates mahogany among neighbouring colour terms in the relevant context.
Local colour vocabulary
Record the naming authority and examples that distinguish its mahogany from nearby reddish-brown or dark-red designations.
- Which palette, supplier or usage community defines mahogany for this decision? provenance
- Which reference samples distinguish its mahogany from chestnut, burgundy, walnut or other nearby names? boundary
Mahogany reference Anchors the named colour to evidence that can support comparison.
Reference authority
Identifies the intended sample or palette definition and its limits.
Reference selection
Record the exact mahogany swatch or palette entry, its origin and whether it governs this application.
- What exact sample, catalogue identifier or palette version is the mahogany reference? provenance
- Does that reference define mahogany only for this product or claim a broader naming scope? boundary
Colour measurement
Describes the reference and candidate in a specified measurement system.
Measured mahogany
Record colour values together with the conditions needed to interpret them, without assigning an unsupported universal mahogany code.
- What are the reference and candidate colour coordinates, and which illuminant, observer and measurement geometry were used? measurement
- If mahogany is supplied as an RGB or hexadecimal value, which colour space and originating palette make that value interpretable? provenance
Mahogany surface appearance Separates colour designation from the surface and viewing effects that shape its appearance.
Substrate and pattern
Captures how the supporting surface contributes to the mahogany appearance.
Uniform or grained target
Record whether the target is a single colour or a distribution of tones whose combined appearance is called mahogany.
- Does the intended mahogany appearance require grain, streaks or translucent depth, or only a uniform colour? definition
- How will light and dark regions be sampled so that a single reading does not misrepresent the target? measurement
Viewing and finish
Specifies the conditions under which the mahogany appearance is judged.
Appearance conditions
Record illumination, viewing arrangement and finish when evaluating the perceived mahogany shade.
- Under which lighting, background and viewing angle must the candidate read as the intended mahogany? measurement
- Does the candidate still match the reference when both are viewed under the additional lighting conditions relevant to use? boundary
Mahogany selection and acceptance Turns the declared colour intent into selection, reproduction and acceptance decisions.
Medium-specific selection
Connects the chosen mahogany reference to the intended output medium.
Mahogany reproduction
Record the rendition chosen for screen, print, textile or coated surface and evidence that it preserves the intended appearance.
- Which physical sample or digital proof demonstrates the selected mahogany in its intended medium? provenance
- What adjustment or alternative reference is acceptable if the medium cannot reproduce the chosen mahogany? action
Match decision
Defines how a candidate mahogany instance is accepted or corrected.
Mahogany acceptance rule
Record the agreed visual or numerical tolerance, assessment result and next action when the match is inadequate.
- What visual criteria or colour-difference formula and threshold govern acceptance against this mahogany reference? measurement
- Should a failed match be adjusted, replaced or escalated for approval, and who can authorise a deviation? 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
Mahogany is a reddish-brown colour category named after mahogany wood, with boundaries that depend on the material, lighting and naming convention.
In scope
- Mahogany as a named reddish-brown colour family
- Context-specific definitions, samples and colour coordinates
- Boundaries with nearby named colours
- Effects of substrate, finish, illumination and reproduction on mahogany appearance
- Criteria for selecting and accepting a mahogany colour match
Out of scope
- Botanical identity and cultivation of mahogany trees
- Identification, provenance and trade classification of mahogany timber
- Mechanical properties and woodworking performance of mahogany
- Chemical composition and safety of stains, dyes and pigments
- Manufacture and structural condition of objects bearing the colour
Why it exists Filled
Enable an agent to recognise, describe, compare and apply mahogany as a colour quality while making its intended reference and viewing conditions explicit.
Distinguishing features Filled
- Establish whether 'mahogany' specifies appearance: a nonwood surface may carry the colour designation without claiming to contain mahogany timber.
- Compare a candidate with the declared mahogany reference under stated conditions; the name alone does not establish a numerical colour match.
- Test boundaries against locally relevant alternatives such as burgundy, chestnut, walnut and burnt sienna using actual samples rather than assuming universal naming thresholds.
- Separate an intended mahogany colour from a reddish-brown appearance caused by lighting, camera processing or a display setting.
- Determine whether the designation covers a uniform colour or the overall appearance of a patterned surface with grain and tonal variation.
What robots and AI may and may not do Filled
Must not
- Present one swatch value as the only correct mahogany.
- Describe a material as mahogany wood because it has the colour.
- Use colour names alone to describe a person's skin or hair in demeaning ways.
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 that its range depends on the naming convention, lighting and medium.
- Match or convert the colour between colour spaces when given a reference value.
Moral aspects Filled
- Calling stained wood mahogany can mislead buyers and hide trade in protected timber.
- Colour words used for people can carry racial connotations.
Who is affected
- Buyers
- Designers and printers
- People described by colour terms
Owners Filled
Steward
Nobody owns it; colour-naming systems differ in their definition.

Open questions
- Does the original registry source confirm that mahogany denotes a colour, as its XCT / XCT.QLT placement suggests, rather than timber or trees?
- Which documented colour references use the name mahogany, and how substantially do their specified shades differ?
- How do relevant usage communities distinguish mahogany from neighbouring reddish-brown colour names?
- For the intended applications, does mahogany require a flat colour match or a combined colour, grain and finish appearance?
- Which viewing conditions and acceptance tolerances are justified for each intended use?
