Summary
Fixes #44894 (content part).
The
color-mix()page's syntax examples already show calls both with and without a hue interpolation method, but it was not explicitly demonstrated that omitting the method is valid and what it defaults to. This PR adds, in the Color interpolation method section, a note and a short example showing that omitting the hue interpolation method when mixing in a polar color space defaults toshorter hue, and thatcolor-mix(in lch, red, blue)andcolor-mix(in lch shorter hue, red, blue)are equivalent.The browser-compat-data part of the issue is tracked separately in mdn/browser-compat-data#28693.
Verification
Verified against the CSS Color 5 spec (csswg-drafts
css-color-5/Overview.bs):<color-interpolation-method>isin [ <rectangular-color-space> | <polar-color-space> <hue-interpolation-method>? ], and the hue interpolation method is not the default (''shorter'') only when explicitly written — i.e. the default isshorter.
