I have hidden lines set to yellow in the system option colors, but the hidden lines for tapped hole threads show up as black, which is difficult to see with a dark background.
Did you go through these options?
It wasn't the highlighted options you had shown, but I ended up running through the whole list under: System Options / Colors and it appears that color for the cosmetic threads from the hole wizard are control by the "Annotations, Non Imported" option
There are times that Color Options can be a challenge to find, thanks for posting your results, a help for the rest of the community..
