[css-values-3] Add link default for color definition Without this fix I was getting the following error from bikeshed: ``` LINK ERROR: Multiple possible 'color' maybe refs. Arbitrarily chose To auto-select one of the following refs, insert one of these lines into a <pre class=link-defaults> block: spec:compositing-2; type:value; text:color spec:css-values-4; type:value; text:color ``` I guess compositing-2 added a definition for color.
