Free Color Contrast Checker

We created a totally free way for you to check the contrast levels of your color combos.

How this tool works

This app tests the contrast levels of the colors in your palette. As long as the level is above a 4.5, then it is considered ‘Compliant’.

WCAG 2.0 level AA requires a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text. WCAG 2.1 requires a contrast ratio of at least 3:1 for graphics and user interface components. WCAG Level AAA requires a contrast ratio of at least 7:1 for normal text and 4.5:1 for large text.

Large text is defined as 14 point (typically 18.66px) and bold or larger, or 18 point (typically 24px) or larger.

How to use the Color Contrast Checker

Simply add any two hex codes, then click 'View Contrast Levels'. You will instantly see the contrast score between the two colors.

If it's above a 4.5, then you're good!

If the level is less than 4.5, then you might want to adjust your color combos to keep things more accessible. :)

NOTE: This tool works best on Google Chrome. It's functional on other browsers, but it works best on Chrome.

    WOW!! Buy it Now

    How did I live without this tool? It literally took me 30 minutes to do what had been taking a week of testing and fretting. I can do everything that is presented in this tool - HOWEVER, after all of the time spent building palettes, testing contrast and style guides I had invested weeks of time and effort.

    Sam has devoted an enormous amount of her love and time into some of the most useful tools a graphic designer can have in their arsenal.

    Do not hesitate. Buy the bundle of Color Palette Builder and Brand Guideline Builder. This will speed up your effective production time and still give you so much flexibility in design control.

    Amazing tool

    I love that this tool allows me to quickly see all complaint colour pairings to ensure palettes I am building are accessible and meet industry guidelines. There is a great range of themes/design styles options but would love to see more.
