Configurable-Module wrong colors in DarkMode for some ->themeColor settings

[horst-n]

Using the new Admin-Theme-Uikit,

when assigning ->themeColor like ''warning" or "highlight" to fields or fieldsets, in LightMode it behaves as expected, (known from the past). In DarkMode it glitches. I have a few screenshots that best can show what I mean:

LightMode, (renders as expected):

DarkMode, (renders with unreadable text-colors and not nice background colors):

` $fieldset->themeColor = 'primary'; $fieldset->themeColor = 'secondary'; $fieldset->themeColor = 'warning'; <-- $fieldset->themeColor = 'highlight'; <--
