opentui: fatal: undefined is not an object (evaluating 'c3[mode2]') #4237
Description
Description
This is triggered when switching to a custom theme with "darkBase": "none". I've verified that the exact same custom theme json file with a normal rgb hex color works.

This issue might be a duplicate of existing issues. Please check:
TypeError: undefined is not an object (evaluating 'c3[mode2]')) at the same location (src/cli/cmd/tui/context/theme.tsx:64:25) when using custom themes with ANSI colorsBoth issues appear to be triggering the same underlying bug in the theme resolution code when using custom theme configurations.
Feel free to ignore if none of these address your specific case.

Ansi colors are not supported.
Sawangg commentedon Nov 12, 2025
@kommander is there plan to add back support for the "none" keyword? The transparency of my terminal is not being respected by the system theme and I was hoping the "none" keyword with a custom theme would do the trick
kommander commentedon Nov 12, 2025
Opentui supports the "transparent" keyword. Not sure how that is mapped currently, but should work. If not, that we can and should fix.
Sawangg commentedon Nov 12, 2025
The transparent keyword throws the same error sadly
I don't know if another issue should be created to support both none/transparent
kommander commentedon Nov 12, 2025
Okay I think I am misunderstanding something here, I all look into it.
