What is the minimum contrast ratio for WCAG AA compliance?

For WCAG AA compliance, normal text requires a minimum contrast ratio of 4.5:1, while large text (18pt or 14pt bold) requires 3:1.

What is the difference between WCAG AA and AAA standards?

WCAG AAA requires higher contrast ratios: 7:1 for normal text and 4.5:1 for large text, compared to AA's 4.5:1 and 3:1 respectively.

How do I fix poor color contrast?

Use our automatic fix feature to adjust either text or background colors while maintaining your design intent, or manually adjust colors using HSL sliders with visual indicators showing optimal zones for AA/AAA compliance.

What are the visual indicators on the adjustment sliders?

The green zones and AA/AAA markers show optimal ranges for achieving WCAG compliance. The direction hints (Lighter/Darker) guide you toward better contrast based on your current color combination.

Can I test custom color combinations?

Yes, you can enter any hex color codes or use the color picker to select custom colors. The URL updates automatically so you can share specific color combinations.

Izindinganiso ze-WCAG

Level AA

Isilinganiso sokuphikisana esincane esingu-4.5:1 sembhalo ojwayelekile kanye no-3:1 wombhalo omkhulu. Okudingekayo kumawebhusayithi amaningi.

Level AAA

Isilinganiso sokuphikisana esithuthukisiwe esingu-7:1 sembhalo ojwayelekile kanye no-4.5:1 wombhalo omkhulu. Kunconyelwe ukufinyeleleka okungcono kakhulu.

Ukungabi khona kokuhlukana okwanele kuzo zonke izincwadi - akuhambisani nezindinganiso ze-WCAG.

Umhloli wokuphikisana kombala

Bala isilinganiso sokuphikisana kombala wombhalo nombala wangemuva.

Khetha umbala usebenzisa i-Color Picker wombhalo nombala wangemuva noma faka umbala ngefomethi ye-RGB hexadecimal (isb., #259 noma #2596BE). Ungalungisa isilayida ukukhetha umbala. I-Web Content Accessibility Guidelines (WCAG) inemihlahlandlela ethile yokusiza ukuthola ukuthi umbhalo uyafundeka yini kubasebenzisi ababonayo. Le mfuneko isebenzisa i-algorithm ethile yokuhlela inhlanganisela yombala ibe izilinganiso ezifanayo. Ngokusebenzisa leli fomyula, i-WCAG ithi isilinganiso sokuphikisana kombala esingu-4.5:1 nombhalo nombala wangemuva sanele kumbhalo ojwayelekile (owomzimba), kanti umbhalo omkhulu (18+ pt ojwayelekile, noma 14+ pt obbold) kufanele ube nesilinganiso sokuphikisana kombala esingu-3:1 okungenani.
