Create An Accessible And Aesthetically Pleasing Interface For Your Users With Our App Design For Colorblindness

Colour-blind people make up a big part of the population – approximately 1 in 12 males and 1 in 200 girls, to be exact. Yet, colour-blind customers are a frequently unnoticed target market in UI layout. Many mistake colour blindness for seeing in black and white, but that is just one type. There are much less uncommon and much less intense versions. Most human beings are trichromatic, meaning they understand colour as an aggregate of 3 colourings: green, red, and blue. Different sorts of colour blindness or colour imaginative and prescient deficiency (CVD) come from not understanding one or more of those colourings clearly. The maximum not unusual place CVD sorts are red-green colour blindness, in which it is difficult to differentiate between red and green, and red colour blindness, in which red colourings seem dull. We at Pearl Lemon Web accept that everybody needs to have truthful and the same get right of entry to the internet, so we provide a design layout with colour-blind customers in mind.

Why Designing For Colorblindness Matters

Colour theory plays a big role in UI design because colour can influence a user’s purchase decision, emotional response, and overall user experience. Just think how important choosing the right brand colour is for your business. Imagine more than 8% of people can’t read your logo or website because of the colours you choose… that’s a lot of missed opportunities.


Colour-blind users cannot distinguish between certain colours, so designers cannot rely solely on colour for their designs’ readability or emotional impact. When using colour, you should consider how users will interact with it and create an interactive design that appeals to your target audience, including those who are colour-blind. It’s the designer’s job to address user pain points with empathy and help users avoid and solve problems.

There are now tools that can calibrate your computer screen for certain types of colourblindness, but not all colour-blind people use these tools.

Note that websites aren’t the only things that need to consider colour accessibility. Even social media can be made accessible to the blind and partially sighted.

Some debate why websites should be designed to meet the needs of such minority populations and minorities. There are several reasons for this:

1) Websites should always strive to be user-friendly for all target groups.

2) some standards make websites accountable to people with disabilities.

3) Well-designed websites do not require modification to be accessible.

Improving app or website design for the colour-blind will also affect other population groups. A growing number of older adults often face similar problems to visually impaired users (e.g. distinguishing between text and elements on a website).

Problems Colour-blind Users Experience When Using Apps

Text Overlaid On Background Images

Overlaying text over images is difficult because some images may not have enough contrast with the text. Decreasing the background opacity increases the contrast and makes the text easier to read. Alternatively, you can customise the text to be a solid colour, drop shadow, or anything else that fits your branding guidelines.

Relative Font Size

Browsers can increase text size (instead of zooming the entire page) to improve readability. However, some browsers disable this feature if font sizes are specified in absolute units such as pixels. Using relative font size units like ems will provide this functionality in all browsers.

Color Combination

In the physical world, you can’t always control adjacent colours: Perhaps a red apple has fallen and nestled in the green grass. However, you can control the colours used to design your website. The following colour combinations should be avoided if possible:

  • green/red
  • green/brown
  • blue/purple
  • green/blue
  • light green/yellow
  • blue/grey
  • green/grey
  • green/black

How To Create An App Design For Colorblindness

Designing for colourblindness does not mean making the product less attractive. This means following certain best practices during the design process. Implementing good UX and UI design principles will only improve the usability of your website or app in the long run.

Use Appropriate Colours

The number one problem with most websites is the wrong background colour. Try to keep your website simple with white or off-white backgrounds and dark text. Don’t forget the colours you use in your graphics and images. Ensure the contrast is different enough so all users can easily read the text. 

It’s also important to consider how you will differentiate sections of your website. For example, make website headings larger than the body text. You can also use a different font for headings. If you primarily use colour to separate headlines from body text, people with colour blindness may have difficulty recognising your headlines.

Use Symbols And Label Everything

Clear labelling is a proven way to guide all users, including those who are colour-blind, into the customer journey. Labels help distinguish information normally conveyed by colour and guide users through diagrams or web pages. Ask yourself if users can navigate without the colour hints you provide.

From an e-commerce perspective, products should have clear and descriptive information. Don’t rely on product photos to tell the whole story.

Don't Forget About The Contrast

It is important to understand that people with colour blindness see the same colourful images as we do. Despite being unable to see some colours, colour-blind people can distinguish between colours better than the average person. As early as 1940, scientists believed that colour-blind people could have normal vision. 

What colour-blind people aren’t always good at is distinguishing between tones (red, yellow, blue, green, etc.). A person with normal vision sees the same image as someone with protanopia. To a colour-blind person, the flowers and the background appear to be nearly the same colour. When it comes to user interfaces, this perception causes many problems.

The text becomes unreadable, and the call-to-action button becomes obscure, and so on. Colour-blind people rely on luminance contrast to identify objects. One way or another, this colour contrast is present in the palette but can be either sharp or muted. The more discreet, the more difficult it is for colour-blind people to distinguish colours.

Add Text Labels

Adding text labels to colour filters and swatches improves accessibility for colour-blind users. Depending on the type of colour blindness, the user may have difficulty distinguishing between shades without descriptive text.

Adding text captions to colour filters improves accessibility for users with normal vision. For example, white, off-white, and light grey are often difficult to distinguish on a monitor.
