I've added an [interactive visualization of the various hue fixup methods](https://observablehq.com/@danburzo/hue-interpolation-fixup), and changed the fixup algorithms to work with any number of hues. Here are the formulas I use currently; they need to be tested more thoroughly, but at first blush they seem correct. ```js // shorter: θ₂ = Math.abs(θ₂ - θ₁) <= 180 ? θ₂ : θ₂ - 360 * Math.sign(θ₂ - θ₁); // longer: θ₂ = Math.abs(θ₂ - θ₁) >= 180 ? θ₂ : θ₂ - 360 * Math.sign(θ₂ - θ₁); // increasing: θ₂ = θ₂ >= θ₁ ? θ₂ : θ₂ + 360 * (1 + Math.floor(Math.abs(θ₂ - θ₁) / 360)); // decreasing: θ₂ = θ₂ <= θ₁ ? θ₂ : θ₂ - 360 * (1 + Math.floor(Math.abs(θ₂ - θ₁) / 360)); ``` -- GitHub Notification of comment by danburzo Please view or discuss this issue at https://github.com/w3c/csswg-drafts/issues/4735#issuecomment-653899931 using your GitHub account
