 Serializing contrast-color() {#serial-contrast-color}
 -----------------------------------------------------
 
-The serialization of the result of a ''contrast-color()'' function
-is a <<color>>,
-as defined in [[css-color-4#serializing-color-values]].
-The form used
-is the same as that used to specify
-the winning color.
+The [=specified value=] of the ''contrast-color()'' function
+is serialized with each keyword value as specified
+and each component in canonical order.
+
+The [=resolved value=] of the ''contrast-color()'' function
+is the [=used color=] serialized the same as any other <<color>>.
