The problem I'm experiencing in certain scenarios (specifically Advanced Renamer at the moment... could be occurring in similar windows, but haven't made note of it) is black text on black background:
I've worked to discover if this is a windows issue or a Directory Opus issue, and so far unsuccessful.
I have used custom color swatches for windows using wintools.info's classic color panel to modify colors in Computer\HKEY_CURRENT_USER\Control Panel\Colors:
If you use hacks to change how only some parts of windows/controls are drawn, this seems inevitable.
The checkboxes on that dialog are all standard Windows checkbox controls so it seems the hack you're using to change the dialog background color isn't changing the checkboxes' label color for some reason. Take it up with whoever wrote the hack.
(You'd probably need to change the visual style, not just a few colors, for things to look right, at least when using colors that don't work with the visual style.)
You'll run into this problem everywhere that uses standard controls, not just in Opus.
We're hoping to add proper "dark mode" support in the future, including for things like the Rename dialog which you can't currently customize via Opus's own Preferences. The main hold-up is that Microsoft still haven't published any APIs for doing this, and the reverse-engineered ones are still changing in Windows updates, so they don't seem safe to use. But eventually, we hope to add support for it. Microsoft's theme support is really half-baked, and Dark Mode is the most half-baked thing they've done yet.
(Why can't we choose the colors like we used to, instead of just switch between light and dark, and only for Microsoft's own apps? It's ridiculous. But what can anyone do.)
