How can I enforce a black font color in CKEditor5Field for dark mode?

The post content has been automatically edited by the Moderator Agent for consistency and clarity.

I have two CKEditor5Fields in my model, and when the browser is in dark mode in the admin panel, the field's background remains white while the font color shifts to off-white, causing readability issues. The rendered page appears fine, so I need a way to set the default font color to black, irrespective of browser dark mode.

My model definition:

PYTHON
property_short_description = CKEditor5Field('property short description', config_name='extends', blank = True, null = True)
description = CKEditor5Field('description', config_name='extends')

And my CKEditor configuration:

PYTHON
CKEDITOR_5_CONFIGS = {
    'default': {
        'toolbar': ['heading', '|', 'bold', 'italic', 'link',
                    'bulletedList', 'numberedList', 'blockQuote', 'imageUpload'],
    },
    'extends': {
        'blockToolbar': [
            'paragraph', 'heading1', 'heading2', 'heading3',
            '|',
            'bulletedList', 'numberedList',
            '|',
            'blockQuote', 'imageUpload'
        ],
        'toolbar': ['heading', '|', 'outdent', 'indent', '|', 'bold', 'italic', 'link', 'underline', 'strikethrough',
        'code','subscript', 'superscript', 'highlight', '|', 'codeBlock',
                    'bulletedList', 'numberedList', 'todoList', '|',  'blockQuote', 'imageUpload', '|',
                    'fontSize', 'fontFamily', 'fontColor', 'fontBackgroundColor', 'mediaEmbed', 'removeFormat',
                    'insertTable',],

        'image': {
            'toolbar': ['imageTextAlternative', 'imageTitle', '|', 'imageStyle:alignLeft', 'imageStyle:full',
                        'imageStyle:alignRight', 'imageStyle:alignCenter', 'imageStyle:side',  '|'],
            'styles': [
                'full',
                'side',
                'alignLeft',
                'alignRight',
                'alignCenter',
            ]
        },
        'table': {
            'contentToolbar': [ 'tableColumn', 'tableRow', 'mergeTableCells',
            'tableProperties', 'tableCellProperties' ],
            'tableProperties': {
                'borderColors': customColorPalette,
                'backgroundColors': customColorPalette
            },
            'tableCellProperties': {
                'borderColors': customColorPalette,
                'backgroundColors': customColorPalette
            }
        },
        'heading' : {
            'options': [
                { 'model': 'paragraph', 'title': 'Paragraph', 'class': 'ck-heading_paragraph' },
                { 'model': 'heading1', 'view': 'h1', 'title': 'Heading 1', 'class': 'ck-heading_heading1' },
                { 'model': 'heading2', 'view': 'h2', 'title': 'Heading 2', 'class': 'ck-heading_heading2' },
                { 'model': 'heading3', 'view': 'h3', 'title': 'Heading 3', 'class': 'ck-heading_heading3' }
            ]
        }
    }
}

I would appreciate any guidance on ensuring the font color defaults to black so that the editor remains readable in dark mode.

Fixing CKEditor5 Font Color in Dark Mode

To ensure your CKEditor5 fields have black text regardless of browser dark mode settings, you can implement one of the following solutions:

Solution 1: Add Custom CSS

Create a custom CSS file and include it in your admin template to override the text color for CKEditor fields:

CSS
/* Add this to your admin CSS */
.django-ckeditor-5-widget .ck-content {
  color: #000000 !important;
}

/* You might also need to target specific elements inside the editor */
.django-ckeditor-5-widget .ck-editor__editable {
  color: #000000 !important;
}

Solution 2: Configure CKEditor with Default Font Color

You can modify your CKEditor configuration to set a default font color by adding the fontColor.colors property to your configuration:

PYTHON
CKEDITOR_5_CONFIGS = {
    'extends': {
        # Your existing configuration...
        
        # Add this section to set default font color
        'fontColor': {
            'colors': [
                {
                    'color': '#000000',
                    'label': 'Black',
                    'default': True
                },
                # Other colors...
            ]
        },
        
        # Rest of your configuration...
    }
}

Solution 3: Use Content Styles Configuration

CKEditor5 allows you to define content styles that will be applied to the editor content:

PYTHON
CKEDITOR_5_CONFIGS = {
    'extends': {
        # Your existing configuration...
        
        # Add content styles configuration
        'contentsCss': ['body { color: #000000; }'],
        
        # Or use the more modern approach
        'content': {
            'styles': [
                'body { color: #000000; }',
                'p { color: #000000; }',
                'h1, h2, h3 { color: #000000; }'
            ]
        },
        
        # Rest of your configuration...
    }
}

Solution 4: Override with JavaScript

If the above solutions don't work, you can add a custom JavaScript snippet that sets the text color after the editor is initialized:

JAVASCRIPT
document.addEventListener('DOMContentLoaded', function() {
    // Wait for CKEditor instances to be initialized
    setTimeout(function() {
        document.querySelectorAll('.django-ckeditor-5-widget .ck-editor__editable').forEach(function(editor) {
            editor.style.color = '#000000';
        });
    }, 500);
});

Include this script in your admin template to ensure the text color is set to black regardless of the browser's dark mode setting.
