Grey or transparent subtitles

Premiere's new color management is a huge step forward, but of course, as in anything human created, not without bumps.

And graphics is one of those items. There are several situations that can trigger graphics being of lower brightness for 'white' than expected, and even having tried, I cannot always reproduce them "on command". Which is frustrating to me also.

There are several things that can help in that moment ... going to the Lumetri panel's new Settings tab, the home of ALL of Premiere's extensive color management options from input through sequence/export.

Selecting the graphic, sometimes simply using the Clip option to disable color management or "Preserve RGB" for that clip works.

Sometimes going to the Input Override section, ticking the Media Override setting, and selecting say the top option, the Arri wide option ... will fix it.

There are a couple other things for certain very specific issues that I  won't take time to explain, but the above will get most graphics displayed correctly.

And yes the staff is aware that there are some issues here.
