I decided to find out what computed color values you get when using #CSS `color-mix()` to change color spaces. The results for HSL and HWB are… interesting. XYZ also did not come out as I naïvely assumed it would. https://codepen.io/meyerweb/pen/pvojrWo
@Meyerweb Yep, the sRGB-derived color spaces are specced to compute back to sRGB, and for the result of the color-mix(), the color(srgb) is preferred because it offers greater precision and doesn’t have web compat issues.
