Free Color Contrast Checker

See if your color pairings have a 4.5+ contrast score!

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.

I'm Obsessed!

I've been a fan of their tools from the beginning, but I've got to say the new Color Palette Pro is the best yet! As a web designer this is the first place I go to take my clients' inspiration and create a palette that's uniquely them, but also meets contrast guidelines. It's so much fun to use I could spend hours just creating amazing palettes. There's so much here, I could go on and on, do yourself a favor and grab this tool!

Hi Megan,

I'm so grateful for your review- thank you! I love your comment about spending hours just playing with the tool- I felt the exact same way when we were working on this new update. I'm glad this makes creating color palettes feel FUN. Thank you!
