Did you try to set explicitly custom configuration in your settings.py like here? GitHub - hvlads/django-ckeditor-5: Django CKEditor 5 integration.
Something like that:
STATIC_URL = '/static/'
MEDIA_URL = '/media/'
MEDIA_ROOT = os.path.join(BASE_DIR, 'media')
customColorPalette = [
{
'color': 'hsl(4, 90%, 58%)',
'label': 'Red'
},
{
'color': 'hsl(340, 82%, 52%)',
'label': 'Pink'
},
{
'color': 'hsl(291, 64%, 42%)',
'label': 'Purple'
},
{
'color': 'hsl(262, 52%, 47%)',
'label': 'Deep Purple'
},
{
'color': 'hsl(231, 48%, 48%)',
'label': 'Indigo'
},
{
'color': 'hsl(207, 90%, 54%)',
'label': 'Blue'
},
]
