Worked decision record
Preserve the same visual colour while converting among HEX, RGB, and HSL, then validate text contrast separately.
Convert `#3366FF` to RGB and HSL, then convert the results back to HEX; compare previews on light and dark backgrounds.
The round trip produces the same colour within rounding tolerance, swatch and picker agree, and every channel remains within its valid range.
Do not move the result into a design system when colour space, alpha, or wide-gamut requirements are lost; check target-platform colour management separately.
