HEXA to HSL
Build shade scales faster
HSL gives teams direct control over lightness ramps for semantic tokens like success-100 to success-900. Starting from HEXA lets you preserve original color intent while re-expressing it in a format many CSS pipelines and design docs find easier to reason about.
Alpha handling
HSL itself has no alpha channel; pair with HSLA if translucency is part of the contract. For round-trips including opacity, use HEXA to HSLA.
