[TB] Shade color in dark mode is showing incorrect on-color

Problem/Concern

Saw this today when testing in preparation for release 1.2.0. I went to Components->Colors->Theme Colors. Notice that the on-color for the Secondary-600 shade is NOT #ffffff or #121212 (which I thought were the only possible values currently), but rather a completely different value. AND the text on that shade isn't visible so certainly the contrast is wrong. Not sure how that weird value is sneaking in there. Happens in both light and dark mode.

Notice that the on color and shade color are the same on that card.
