I think we need to fix fhe variable for these themes. See

server/apps/theming/lib/Themes/DarkTheme.php

Line 56 in 6003f8c

$colorMainBackgroundRGB = join(',', $this->util->hexToRGB($colorMainBackground));

and

server/apps/theming/lib/Themes/DarkTheme.php

Line 68 in 6003f8c

'--color-main-background-rgb' => $colorMainBackgroundRGB,
