Description Adam Argyle 2021-08-30 11:06:24 PDT 
Looks like system colors don't work as a value to be compared against. Reduced test case here: https://cdpn.io/argyleink/debug/bbaf6bf6aa72419da3bd53f5eee85329


Maybe system colors also aren't potential candidates in the list of valid comparison colors either?

```
// FIXME: We don't have enough context in the parser to resolving a system keyword
// correctly. We should package up the relative color parameters and resolve the
// whole thing at the appropriate time when the origin color is a system keyword.
