textual: Command palette modal makes data table zebra stripes the wrong color in light mode

Run python docs/examples/widgets/data_table_cursors.py from a repo clone, and use the command palette to switch to light mode:

Then open the command palette, and while the modal is displayed note that the zebra stripes change colors past the last column containing data (to lilac or light purple):

This doesn’t seem to happen in a dark mode theme:

Well, let’s set aside the question of whether Textual should be enabling true color mode for my terminal or not, and focus on whether Textual’s behavior is right or wrong when 256-color mode is being used instead of true color mode.

This is what I was hinting in my post before last, I think you make some good points. But I’m not a maintainer of Textual, just an ~annoying hanger-on~ eager contributor, so I think I should bow out here.

Perhaps you could try export COLORTERM=truecolor?

That does make what I see match your screenshot.

Presumably also this is due to 256-color limitations and looks fine on terminals with true color support.

I would suspect this is a ModalScreen effect, not really the CommandPalette specifically.
