Common contrast mistakes designers make

  • Designers often overlook how their designs appear in dark mode, making text hard to read due to low contrast. Always test your designs in both light and dark modes to ensure text stands out in both settings.

  • While dark backgrounds with light text can look sleek, low contrast can make emails hard to read, especially for users in dim lighting or those with visual impairments. Ensure the contrast ratio meets accessibility standards.

  • Logos on dark backgrounds may be hard to distinguish, especially in dark mode. To improve brand recognition, use logos with sufficient contrast against backgrounds and test for visibility in both modes.

  • Relying on color alone to convey meaning can exclude users with color blindness. Always pair color with text or symbols to make information accessible to everyone, regardless of their vision.

  • Designs that look good in bright environments can struggle in dimly lit settings. Ensure your text remains legible in various lighting conditions to avoid frustration for users in low-light environments.
