I have a project that uses the denver theme with @palette="ice-fire", and there have been no problems building it in the past.  After updating to pretext 2.22.0, I see

Building custom css theme: theme-denver
error: ✘ [ERROR] "Unknown color scheme ice-fire for theme. Valid schemes are: blue-red, blue-green, green-blue, greens, blues"

Those look like the valid schemes for the default-modern theme.  I'm declaring the theme in
publication/html/css

Did I miss a change or is this an issue that showed up in 2.22.0?

Thanks,
David

I can confirm this behaviour (setting is in the publication.ptx file)
Seems to be an error. At least the documentation (https://pretextbook.org/doc/guide/html/publication-file-online.html#online-style-options) lists ice-fire as a valid palette for both salem and denver themes.

Yes, this is a bug.  Fixed in 2.23.0.
