Dark Mode Palette Builder

Dark mode has transcended being a niche feature to become a user expectation for modern applications. It's not just about aesthetics; a well-implemented dark theme offers tangible benefits for both users and their devices.

Key Benefits of Dark Mode:

• Reduced Eye Strain: In low-light environments, a dark background with light text is significantly less harsh on the eyes than a bright, white screen, reducing visual fatigue.
• Improved Battery Life: On devices with OLED or AMOLED screens, black pixels are "turned off," consuming no power. A dark UI can lead to noticeable battery savings on these devices.
• Enhanced Focus: Many users find that dark mode helps them focus on the content itself, as the surrounding UI recedes into the background. It minimizes glare and can make content like photos and dashboards pop.
• User Preference & Accessibility: Some users with light sensitivity or certain visual impairments find dark themes more comfortable to read. Offering a choice respects user preferences and improves overall accessibility.

However, creating a good dark mode is more complex than simply inverting colors. Naively inverting colors often results in a high-contrast, jarring experience that is worse than the light theme. A thoughtful approach is required.

This tool provides a strategic approach to generating a dark palette, giving you control over the key transformations needed for a balanced and brand-aligned theme.

1. Base Palette Input: Start by defining your primary brand colors. We've pre-filled some common names like "Primary" and "Accent," but you should name them according to your own design system (e.g., brand-500, success-fg).
2. Algorithmic Conversion: The tool doesn't just invert colors. It uses color theory to create a harmonized dark palette.
   • Background & Text: Special logic is applied to your main background and text colors. Typically, a light background becomes a very dark gray (not pure black) and light text becomes off-white. This avoids the harsh contrast of pure black and white.
   • Other Colors: For other colors, the tool intelligently decides whether to lighten or darken them based on their initial brightness. Very light colors are darkened, while already dark colors might be lightened to ensure they are visible against the new dark background.
3. Fine-Tuning Controls:
   • Darken Amount: Controls the overall darkness of the generated colors.
   • Desaturate Amount: Reduces the saturation of colors. Sightly desaturated colors often feel more natural and less "glowy" in a dark theme.
   • Hue Shift: Subtly shifts the hue of all generated colors. A small shift can sometimes create a more cohesive feel across the palette.
4. CSS Variable Export: The final output is provided as ready-to-use CSS custom properties, making it easy to integrate into any project that supports light/dark theming.

A solid color palette is the foundation. Build out the rest of your UI with these tools:

• Neumorphism CSS Generator: Create soft, modern UI elements that work beautifully with nuanced dark themes.
• WCAG Contrast Checker: After generating your palette, use this tool to verify that your text is readable against its new background color in dark mode. This is a critical step for accessibility.
• Gradient Generator: Add depth and visual interest to your dark mode backgrounds.
