Type Alias ContrastAlgorithm

ContrastAlgorithm:
    | "APCA"
    | "DeltaL*"
    | "DeltaPhi*"
    | "Michelson"
    | "WCAG21"
    | "Weber"

Supported contrast calculation algorithms.

Each algorithm has different characteristics, use cases, and output ranges:

'APCA': Modern algorithm designed for text readability, outputs -108% to 106%
'DeltaL*': Simple lightness difference used in Material Design, outputs 0-100
'DeltaPhi*': Extended lightness difference that includes chroma, outputs 0-100+
'Michelson': Classic formula for optical contrast, outputs 0-1
'WCAG21': Web accessibility standard, outputs 1:1 to 21:1
'Weber': Classic psychophysical contrast formula, outputs 0 to ∞
