It’s important to create digital content that everyone has access to, regardless of ability or disability. In this case, ethical and legal play roles in inaccessibility. Businesses, content creators, and designers must understand the law.

Now, many countries are also starting to implement rules to ensure commercial websites and apps meet specific requirements for accessibility. Shorter content, like PowerPoint presentations, is the backbone of communication, training, and sales, so there’s no reason to let accessibility standards drop.

One of the most common mistakes we see when it comes to accessibility in presentations is poor color contrast, so many people don’t have access to your presentation. Fortunately, we can fix these common mistakes.

Take me straight to the color contrast checkers for PowerPoint!

What is color contrast?

Color contrast is the ability to distinguish between two colors that appear next. For example, purple has a high contrast with yellow, and blue contrasts with orange. Meanwhile, colors that appear directly opposite on the color wheel have the highest contrast.

Why do you need color contrast checkers for PowerPoint?

To improve accessibility, we should make color contrast checkers for PowerPoint. Poor contrast makes it difficult for the Audience to read and interpret graphs and diagrams. Audiences can read slides that have high contrast with the background fill color.

For the following reason, some students with visual impairment or color deficiency have difficulty distinguishing between colors that have lower contrast levels.

Adequate color contrast under Federal Regulations in online content, with a contrast ratio of at least 4.5:1 for standard text. There are a few exceptions to this rule, including:

  • Large text (14 points and bold or larger, or 18 points or more significant) must have a contrast ratio of at least 3:1
  • Incidental text or text images, which are purely decorative and do not serve the user’s purpose, do not have to meet color contrast requirements
  • Brand logos do not have to meet color contrast requirements
  • Color palette with contrasting shades of blue
  • When color contrast results in better designs

It would help if you had color contrast checkers for PowerPoint for the two reasons above.

Scenarios demand that we have good contrast

Many scenarios demand that we have a good contrast:


The first scenario is delivering a presentation remotely. So you can’t control the slide show of the Audience.


A common problem with projector use is a low-quality projector in poorly lit rooms. Suppose you try to use the projector in the sun, then you will find it difficult to read the content on the screen. The slide will look blurry and challenging to interpret.


You need to make sure everyone can easily read the content through the presentation slides you send.

Some of the sample scenarios above illustrate the importance of adequate color contrast checkers for PowerPoint. The key to the Audience reading your slides is color contrast.

Color contrast can be tricky and depends on many factors. If you want to start making your designs easier for people to access, we recommend looking at the Web Content Accessibility Guidelines (WCAG). These guidelines are the basis of most of the world’s web accessibility laws.

There are three levels: A, AA, and AAA. Most organizations should meet level A and level AA guidelines and be suitable for people with disabilities. According to this level, there are two critical success criteria that you should achieve in terms of color:

The key to coloring success

Luckily, you have found this article. So you can determine the best color contrast and free color contrast checkers for PowerPoint.

Don’t use color as the only visual means of conveying information, but add additional visual cues

The simplest example is using green and red in a circle. For color-blind people, distinguish two processes: one green circle and one red circle.

A simple fix could be with, for example, one green circle with a white tick in the middle and a red ring with a white X.

Color contrast checkers for PowerPoint is sufficient

The second criterion has to make sure the Audience can read all of the slide content.

For the Audience to read written content, the text must have the highest possible contrast with the background color.

For example, to increase the contrast between the text and the background, you can do something like this: The location is white with the text black. The dark gray background is light blue text.

According to WCAG, for text, the contrast ratio should be at least 4.5:1, except for text at least 18pt or at least 14pt and bold (3:1 minimum ratio). Also, font size and weight will affect text contrast and legibility, so it’s best to avoid overly stylized fonts and put a lot of text on one slide.

How do you make color contrast checkers for PowerPoint?

There a free color contrast checkers for PowerPoint and simulators online, such as BrightSlide, WebAIM, and many others. 

Use the BrightSlide

However, most require you to manually enter the HEX code of the color you are using or upload an image of your text. It is inefficient, especially if you have more than a few slides. Therefore, this causes most people not to routinely perform color contrast checkers for PowerPoint.

Once you have entered both sets of RGB, WebAIM will compare your contrast and report.

The “Contrast Ratio” number is the same as BrightSlide at 4.5:1 for standard text, or 3:1 for large text (large text defines as 14 points and bold or more significant, or 18 points or greater).

WebAIM provides a clear read on your ratio and explains how to fix it if it doesn’t meet WCAG standards. WebAIM helps you lighten or darken colors if your balance doesn’t meet the minimum requirements by including a good explanation of ratios and directing you to some more useful online tools.
