I couldn’t find a list, so here it is –
-webkit-column-rule-color -webkit-column-rule-color -webkit-column-rule-color -webkit-print-color-adjust -webkit-print-color-adjust -webkit-print-color-adjust -webkit-tap-highlight-color -webkit-text-emphasis-color -webkit-text-emphasis-color -webkit-text-emphasis-color -webkit-text-emphasis-color -webkit-text-fill-color -webkit-text-fill-color -webkit-text-stroke-color -webkit-text-stroke-color background-color border-bottom-color border-bottom-color border-bottom-color border-left-color border-left-color border-right-color border-top-color border-top-color border-top-color border-top-color flood-color lighting-color outline-color stop-color
Note that this changes over time as new features are added, and by browser, and potentially what types of DOM elements you use, so you may want to look at getting a list of all CSS color properties.
