What’s included in our color contrast checker?
Silktide’s color contrast checker is part of our accessibility toolbar. By ensuring sufficient contrast between text and background colors, you’ll create a better experience for people with visual impairments. You’ll also be a step closer to meeting global accessibility standards, like WCAG and ADA.
Why does color contrast matter for accessibility?
High-contrasting color is a critical part of web accessibility, especially for users with visual impairments, including color blindness, low vision, or aging-related vision loss.
- Insufficient contrast makes content harder to read, leading to frustration and exclusion.
- Sufficient color contrast ensures your website more closely aligns with accessibility standards like WCAG and ADA
- Improving contrast boosts usability for everyone, including users browsing in low-light or high-glare environments.
‘Use of Color’ is part of WCAG Guideline 1.4: Distinguishable.

How does poor contrast impact people with vision impairments?
Users with visual impairments often face significant challenges when websites lack sufficient color contrast:
- Color blindness: Difficulty distinguishing between colors like red and green.
- Low vision: Struggles to read text that doesn’t stand out from the background.
- Aging eyes: Reduced contrast sensitivity makes web content harder to read.
Disability simulations are included, so you can see the effects of poor color contrast on the page you’re testing.
Color contrast and global accessibility laws.
Most global accessibility laws have a basis in the Web Content Accessibility Guidelines (WCAG). So ensuring proper color contrast isn’t just good for usability—it can be a legal requirement.
- WCAG Guidelines: The Web Content Accessibility Guidelines (WCAG) require sufficient contrast for text and graphical elements.
- ADA Compliance: The Americans with Disabilities Act (ADA) enforces web accessibility based on WCAG standards.
- European Accessibility Act (EAA): Upcoming legislation requiring accessibility compliance for businesses in the EU by 2025.
