Visual impairments such as color blindness, cataracts, or low vision can make it difficult for people to distinguish between colors and visual elements.

Venngage helps you create beautiful, engaging, and inclusive designs that remain clear and understandable for all viewers, ensuring your message reaches everyone.
 

A user on Venngage's free color blind simulator page scrolls down the page, showing different headings on the page and changing the preview image with filters representing different visual impairments: regular vision, achromatopsia, deuteranopia, protanopia, tritanopia, cataracts and low vision.

 

 

Check Your Design’s Accessibility

Use Venngage’s free Color Blind Simulator to preview how your website or image appears to people with different visual impairments.
 

A user scrolls down Venngage's free Color Blind Simulator page. The page has the title 'Color Blind Simulator' and a subheading that reads 'Break down visual barriers with Venngage's free color blind checker.' The user scrolls past the subheading, to a section with a Venngage template in a preview pane on the left, and a list of different color blindness or visual impairment conditions. Above the preview pane, a text field for entering a website address appears; the user types 'venngage.com' in the text field. In the preview pane, the home page of Venngage.com appears; the user clicks on one of the conditions in the right bar, beside the preview pane, to change how the website appears.


Here’s how:

  • Go to the Color Blind Simulator page.

  • Paste your design, website, or image link into the URL field.

  • Use the right sidebar to apply different filters and see how your design changes under each vision type:

    • Regular Vision: All primary colors and their shades can be clearly distinguished.

    • Achromatopsia: Complete color blindness — everything appears in shades of grey, black, and white.

    • Deuteranopia: Difficulty detecting greens — most colors appear in shades of blue, yellow, or brown.

    • Protanopia: Difficulty detecting reds — most colors appear in shades of blue, yellow, or brown.

    • Tritanopia: Difficulty detecting blues and yellows — most colors appear in shades of green, red, or pink.

    • Cataracts: Cloudy vision that reduces contrast — makes it harder to distinguish between similar colors or shades.

    • Low Vision: Blurry and decreased vision — makes it harder to see small elements, text, or similar color tones.

       

      A user scrolls down Venngage's free Color Blind Simulator page. The page has the title 'Color Blind Simulator' and a subheading that reads 'Break down visual barriers with Venngage's free color blind checker.' The user scrolls past the subheading, to a section with a Venngage template in a preview pane on the left, and a list of different color blindness or visual impairment conditions; the user clicks on the conditions and the preview pane changes according to what the user clicks, changing the colors in the preview template or blurring it.

As you switch filters, you’ll see exactly how your design appears to users with different vision levels, helping you fine-tune colors and contrast for accessibility.

 

Try It Directly in the Venngage Editor

Before finalizing your project, you can also test it using the built-in visual simulator in Venngage’s upgraded Editor.

We’ve included a sample templates that shows how a single design appears through various visual filters, from different types of color blindness to blurred or cloudy vision — ensuring your final design looks great and stays accessible to everyone.

A series of the same design created in the Venngage Editor; it shows a square social media graphic with an icon of a chef and informational text about a meal charity drive for kids in need. The design is filtered so that it appears as viewers with different visual impairments would see it, including several different color blindness conditions, blurry vision, cataracts, etc.


💡Tip

When designing, aim for strong color contrast, clear text, and distinct visual elements. Avoid relying on color alone to convey meaning—use icons, labels, or patterns for clarity.

By taking a few extra steps to check accessibility, you’ll ensure your Venngage designs are not only beautiful but also inclusive and impactful for every viewer.
