Pastel colors are high-lightness, low-saturation color tones that impart a gentle, friendly, and calming visual aesthetic to web applications, mobile apps, and brand assets.
When used thoughtfully, pastel schemes create a welcoming environment that reduces cognitive fatigue for users.
Information

Key Rules for Pastel Web Design #
- Pair Pastels with Dark Slate Text: Because pastels have high luminance, white text will fail WCAG contrast checks. Always pair pastels with dark slate

- Contrast Borders: Frame pastel cards with subtle dark-tinted borders to define clear visual container boundaries.
Pro Tip
