Designing Blog Post Layouts for Presenting Website Colour Contrast Checks
Colour contrast is one of the fastest ways to make or break a blog post's readability. When you publish tutorials about testing text and button contrast, the layout itself should practise what it preaches. On design-logix.co.uk we build article templates that guide readers through contrast checks step by step, so the page doubles as a demonstration. This post outlines a practical layout for a contrast-checking tutorial.
Start with a Plain-Language Intro Section
Open with two short paragraphs that explain why contrast matters for readability. Mention WCAG 2.1 AA thresholds: 4.5:1 for normal text and 3:1 for large text and interface components. Keep the tone practical rather than legal.
Use a neutral background and body text that already passes 7:1, because readers will judge your credibility by the page they are reading. Add a short blockquote that frames the goal:
If readers squint, the layout has already failed, no matter how clever the copy is.
Show a Colour Pair Table Before the Steps
A table lets readers scan passing and failing combinations at a glance. Keep the header row simple, and use short labels so the table stays readable on mobile screens.
| Foreground | Background | Ratio | Result |
|---|---|---|---|
| #1A1A1A | #FFFFFF | 17.4:1 | Pass AAA |
| #777777 | #FFFFFF | 4.48:1 | Borderline |
| #999999 | #FFFFFF | 2.85:1 | Fail |
Place the table before the walkthrough so readers can see the destination before the journey. Then repeat the key ratios in the numbered steps below.
Write the Testing Steps as an Ordered List
Numbered steps reduce cognitive load because readers always know where they are. Each step should contain one action, one tool, and one expected outcome.
- Pick a foreground and background pair from your design system.
- Paste the hex codes into a contrast checker and record the ratio.
- Compare the result with the 4.5:1 and 3:1 thresholds.
- Adjust lightness, not hue, until the pair passes.
- Re-test the button label against its hover and focus states.
After the list, add a bullet list of common mistakes so readers can self-correct. Keep each bullet under two lines.
- Testing only the default state and ignoring hover colours.
- Using thin font weights on low-contrast backgrounds.
- Assuming a ratio of 4.5:1 works for every font size.
Add a Button State Demo Section
Buttons need separate checks because their text often sits on saturated fills. Create a small grid of default, hover, focus, and disabled states, then annotate each with its measured ratio.
If a state fails, show the corrected version beside it rather than hiding the failure. Readers learn faster from before-and-after comparisons than from a perfect final result.
Close with a Quick Reference Checklist
End the article with a compact checklist that readers can copy into their own workflow. Link to a contrast checker and remind them to re-test after every colour token change.
Finally, keep your own page clean: generous line height, no text over images, and visible focus rings. A tutorial about contrast should never need an apology for its own design.
