Doubt

The purple color is used to indicate tracked values. In this picture, the grey values are probably from the home position or home preset of the fixture and haven't been recorded in any previous cue.

OP was asking about Thema purple background color of selected parameters. I can still see it in Blind but not in Live.

pity, it was helpful....It was a great help for those of us who are very clueless

No, it's not about traked values ... simply Group 12 @ FF, before it marked the intensity level with a purple background ... now it does not ... and that was helpful ...
