If you want a particular direction, you can specify the angles to cause that direction, just like you do with 'rotate' Suppose I have ``` --start: `lch(52% 58.1 22.7) --end: lch(56% 49.1 257.1) // currently, this goes the long way around mix-color(var(--start) var(--end) hue(75.23%)); // 22.7 * 0.7523 + -102.9 * ( 1 - 0.7523 ) = -8.41112 // mixed result is lch(52% 58.1 -8.41112) ``` You seem to be saying that going the other way round I would need to inspect the values of the two custom properties and if needed, add or subtract 360 to make it do what I want. ``` --otherend: lch(56% 49.1 -102.9) // now it goes the short way around mix-color(var(--start) var(--otherend) hue(75.23%)); ``` while what I am suggesting does not require making adjusted copies of custom properties: ``` // this would go the short way around mix-color(var(--start) var(--end) hue(75.23% short)); // this would go the long way around mix-color(var(--start) var(--end) hue(75.23% long)); // new default if unspecified, go the short way around mix-color(var(--start) var(--end) hue(75.23%)); ```` -- GitHub Notification of comment by svgeesus Please view or discuss this issue at https://github.com/w3c/csswg-drafts/issues/4735#issuecomment-597670841 using your GitHub account
