The 7 Best Online Contrast Checker Tools in 2021

I love testing online color tools and reviewing them. The inside color blog has previously published articles about online gradient generator, color palette generator, color converter, color wheel, and color blender tools and we found them very useful to designers and creatives alike. Let’s take a look at the 7 Best Online Contrast Checker Tools in 2021!

What Is Color Contrast Ratio?

In the context of web accessibility, color contrast ratio determines the difference between the light levels in the foreground and background.

These days, using mobiles and computers are inevitable. Therefore, if you wish to reduce the strain on your eyes, you should consider the contrast between the elements on your screen. A person who is Colorblind may also be hypersensitive to certain colors or shades of light, and they may experience pain if a text’s color fails to contrast with its background. That is why contrast is so crucial when designing a web page.

What is WCAG?

A set of Web Content Accessibility Guidelines (WCAG) was developed by the W3C process in collaboration with individuals and organizations in every country of the world, addressing individuals’, organizations’, and governments’ needs regarding web accessibility. Web “content” generally refers to the information in a web page or web application, including natural information such as text, images, and sounds and code or markup that defines the structure, presentation, etc.

The WCAG has been published in three different versions, 2.0, 2.1, and 2.2. If you want to know more, then check out this article about Web Content Accessibility Guidelines in Wikipedia.

What is Contrast Checker Tools?

Color Contrast Checker is a tool that tests the contrast ratio of your background and text for accessibility. It will also indicate if the colors pass the newer WCAG 2.0 contrast ratio formula. You can use the contrast checker to determine whether your colors combine well.

Dopely Color Contrast Checker helps you determine the accessibility of your text size, color contrast, and spot checks your visual elements.

Additionally, you have the option to choose your colors randomly.

Currently, Dopely’s color contrast checker is limited to two color systems, but that’s not a problem. Since Dopely is an integrated software package, you can easily convert your color code to 20 different color systems.

WebAIM contrast checker design supports hexadecimal or RGB code. A color wheel is also available to select the color. There is only a lightness roller for adjusting contrast.

Coolors provide an interesting quote instead of a common text that you can see the changes on. Coolors doesn’t have a color extractor tool in its contrast checker so if you want to choose a color in a picture, you have to know the name.

5. Colour Contrast Free Online Contrast Checker Tool

Colour Contrast feature is almost similar to the others; You can use a hex code to select the background color and text color, then adjust the hue, saturation, and lightness to achieve the right combination. It would be better to have a color picker tool, but there isn’t one. As an interesting feature, you can choose the fonts and see the contrast between colors in two sizes of text.

Deque is the only color contrast checker in this list that allows users to select colors by name but There are only 120 names on this list, which is a small number when you consider 16 million colors. Additionally, you can choose colors in hex and RGB codes, as well as through the color wheel.
Despite not being completely professional, the design is mobile-friendly.
