Pro Tools Studio - used Buses not yellow

[[email protected]]

Noob PT user for a few weeks.
When I used to select a Send bus, used buses would show in Bold yellow font making it easy to know whats in use and what's available to assign.

Not sure when this happened, but now, when I go to select a send, the used buses do not show in yellow anymore. Upon closer look, used buses are in Bold font, but not real easy to tell what's in use since they are all white.

Any idea on how to get the font to be yellow again on used Buses?
Thanks

I found out what this was - Color Palette/General/Text saturation was set to 0 for some reason. Reseting it back to 100 brought the 'used bus indicator' text back to yellow.
