The political side of colors has reversed in the US: red is now for conservative states and blue for liberal states (within the US range, which from almost Christian Democrats to nearly Social Democrats, but not quite). The red and blue, if based on the litmus test (I can't remember which is which now), is a little more universal. Even black and white don't have universal symbolism. So we would have to think any such usages through very carefully.
This not a bad idea and might be expanded to emotions and the like, though the connections there are even more culture bound (even subculture, see "blue").
