本番導入前にグラデーションをテストする方法

公開前に短いチェックを行い、可読性・一貫性・状態別の見え方を確認する手順です。

デザイン上で良く見えても、実装状態では崩れることがあります。

Start with one clear UI goal

Decide whether the gradient should separate sections, emphasize a block, or create depth.

One goal makes direction, colors, and intensity easier to control.

Choose two colors before adding complexity

Two stops are usually enough for clean interfaces.

Only add a third color if it solves a specific visual problem.

  • Use nearby hues for subtle depth.
  • Use stronger contrast only on focal sections.
  • Check readability before locking colors.

Pick linear or radial based on layout shape

Linear gradients fit headers, cards, and directional flow.

Radial gradients fit spotlight-style emphasis behind one focal element.

Always validate with real text and components

Test the gradient behind real heading sizes, buttons, and cards.

If readability drops, reduce saturation or add a soft overlay.

Practical use cases

  • Landing page hero backgrounds.
  • Section dividers with subtle depth.
  • CTA blocks that need clearer visual focus.

Use gradients as support, not decoration

Start with clarity, test quickly, then ship a gradient that helps the layout instead of competing with it.
