Evidence methodology

Recommendation evidence and taxonomy method

MyToneMatch shows the scope and uncertainty of reviewed evidence instead of scores or hidden rankings.

Taxonomy independence

MyToneMatch Korean 8-Type v1 is shared across the Korea, US, and Global markets. Western 12-Season v1, PCCS tone vocabulary, and provider-authored raw classifications remain separate identities; similar names never create aliases or automatic conversions.

Recommendation levels

• recommended
• conditional
• not_recommended
• insufficient_evidence

Not recommended requires reviewed conflicting evidence. Missing evidence is insufficient evidence, not a negative recommendation.

Independent review decisions

Attribute verification, type classification, and recommendation publication are separate decisions. We use individual review or previously approved classification criteria; ambiguous shades and insufficient evidence remain pending further review. Collecting a product does not by itself publish a recommendation.

Display order and commerce

Popular, newest, and price sorting do not represent personal-color suitability rankings. Price, stock, and affiliate terms never alter recommendation state or evidence confidence.
