To check gradients and backgrounds on any website, inspect the page in layers: first the visible sections, then the background fills, then gradients, overlays, and contrast against the content above them. The useful result is a record of where each background appears, what role it plays, and whether it supports or competes with the content.

Use a repeatable inspection method

Start at the top of the page and work downward. For every major section, record:

  1. The background type: solid color, image, video, gradient, transparent overlay, or a combination.
  2. Where it begins and ends: hero, navigation, feature section, card, footer, or full-page background.
  3. Its visual role: separating content, emphasizing an action, creating depth, supporting media, or setting the overall mood.
  4. The contrast result: whether headings, body copy, buttons, and small labels remain easy to distinguish.

Check a narrow viewport as well as desktop. A gradient or image that looks balanced on a wide screen may place its brightest or darkest area behind important content on mobile.

The example below is a captured Pangram AI Detector page described as using a muted green direction. Use it as a visual comparison, not as a claim about the site you are reviewing. The accompanying palette includes dark greens such as #15502e, #14532d, and #233f2a, along with lighter muted tones such as #556659 and #799c92. Treat the colors as observed references, not as a complete palette or a recommendation for every role.

How to identify a gradient

A gradient usually reveals itself through a gradual change in hue, brightness, or transparency. Look for a dark-to-light transition behind a hero heading, two neighboring hues blending across a section, a colored glow behind an illustration, a transparent color fading into the page background, or a radial highlight around a card or screen.

Write down the direction and approximate stops in plain language first. For example: "Deep green at the lower left, muted sage toward the upper right, with a soft transparent fade behind the heading." This is more useful than recording one average color.

Then check whether the gradient changes the reading order. If the brightest area sits behind a small button or light text, the design may need a stronger overlay, darker text, or different stop positions. If the gradient is decorative, it should not make the main content harder to scan.

Check backgrounds by role

Separate the page background from component backgrounds. A pale section surface, card fill, and button color may look similar in a screenshot but serve different jobs. Record each role separately:

  • Page background: the default canvas behind most content.
  • Section background: a visual break between content groups.
  • Surface background: cards, panels, navigation, and controls.
  • Media background: the color or overlay behind an image or video.
  • State background: hover, selected, warning, success, or disabled states.

Note repetition. A strong color used once can act as an accent. The same color used across most sections becomes part of the page identity. Check whether borders, shadows, and radii reinforce the same system or introduce unrelated treatment.

Turn observations into a usable checklist

Before copying a background treatment, ask:

  • Does it improve grouping or only add decoration?
  • Does text remain readable at normal and narrow viewport sizes?
  • Does the image or video remain separate from nearby content?
  • Are gradients consistent in direction and intensity?
  • Are light and dark surfaces used with a clear hierarchy?
  • Can the treatment work without one specific image?
  • Does the color still work for buttons, links, and focus states?

For a practical handoff, describe the treatment as named tokens and rules: page-bg, section-bg-muted, hero-gradient-start, hero-gradient-end, surface-border, and overlay-opacity. Include the section where each token appears and a short contrast note. A captured website review can inspect page structure, colors, gradients, spacing, borders, shadows, and component styles, then help turn observations into CSS or Tailwind notes.

Use this in your AI agent

> Check the captured website's backgrounds section by section. Identify solid fills, gradients, image and video overlays, surface colors, borders, shadows, and contrast relationships. Describe each treatment by location and visual role, then produce a compact token list with suggested names such as page-bg, section-bg, hero-gradient-start, hero-gradient-end, and overlay-opacity. Separate observed details from recommendations, and flag areas where text or controls may lose contrast. Compare the result with the muted green example without assuming it belongs to the target site.

What should I record when a website uses several overlapping gradients?

Record each layer separately instead of flattening the result into one color. Start with the base background, then note the gradient direction, approximate color stops, opacity, blend behavior if visible, and the element it sits behind. For example: "Solid deep green section, radial sage glow behind the product image, black transparent overlay under the heading."

Also record the likely purpose of each layer. It may separate white text from an image, guide attention toward a button, soften a hard edge, or create depth behind a card. If two layers serve the same purpose, mark that as a possible simplification rather than assuming both are essential.

Check the treatment at the narrowest useful layout. A gradient may move relative to the content when columns stack, and an overlay that works behind a desktop image may become too dark or too bright on mobile. Include the section, layer order, approximate strength, and any responsive change in your notes.

How can I turn my background notes into design tokens?

Group the notes by function, not by the order in which colors appeared. Create tokens for the page canvas, muted sections, raised surfaces, borders, overlays, and accent backgrounds. Then create gradient tokens that describe their purpose and stops, such as hero-gradient-start, hero-gradient-mid, and hero-gradient-end.

For each token, include the observed value or a clearly marked approximation, where it appears, and whether it is used with light or dark content. Keep recommendations separate from observations. A useful handoff might say: "Observed: dark green base with a lighter green glow behind the illustration. Recommendation: use the glow only in the hero and keep feature sections on a flat surface."

Test the tokens against headings, body text, buttons, and images before applying them site-wide. This prevents a color that works as a decorative gradient stop from being reused as a text or control color without enough contrast.
