What is Color Blindness and How Does It Happen?

When you are unable to see colors properly, called color blindness or color vision deficit, it is also known as color blindness. This condition is also called color blindness. It is when a person cannot differentiate between certain colors. This is usually between reds and greens, but occasionally it can also occur in blues.

Two types of retina cells can detect light. These cells are known as rods and cones. They are located near the center of your eyes and detect color. There are three types of cones that see color: blue, green and red. These cone cells provide input to the brain that determines our perception of color. You can develop color blindness later in life, although it is more common to be born with. A more serious condition can be indicated by a change in your color vision. An ophthalmologist should be consulted if there is a marked change in color perception.

Why is color important for data visualization?

Data visualization is a key factor because it helps you highlight important information and encourages information recall. Different color‘s can be used to separate and delineate different data points in a visualization, so viewers can clearly see significant differences or similarities. You can also use it to stimulate emotions through color psychology.

Understanding Color Blindness and Color Perception

Color blindness, AKA known as color vision deficiency, is a situation that influences an individual’s capability to distinguish between particular colors. The most common is red-green color blindness, followed by blue-yellow color blindness. Some color-blind people can still discover colors to some extent but may struggle with particular color combinations.

Designing Color Blind Friendly Palettes PowerPoint

For your blind presentation, you should consider the following factors:

  1. Use High Contrast: Opt for high contrast between text and background colors. A light color on a dark background or vice versa ensures legibility for all users.
  2. Avoid Color Coding Alone: Refrain from relying solely on color to convey information. Include labels, symbols, or patterns that provide context and clarity.
  3. Test with Simulators: Utilize online color-blindness simulators to preview how your content appears to color-blind users. This helps you identify potential issues before finalizing your presentation.

Good and Bad color blind friendly palette PowerPoint example

Here are some examples of color-blind friendly palette PowerPoint to understand it better:

Good Example:

  • A color chart that utilizes both color and pattern differentiation. For instance, a bar graph with different hatch patterns for each bar along with distinct colors.

Bad Example:

  • A color chart that solely uses different shades of red and green to differentiate data points. This is problematic for red-green color blind individuals who might struggle to distinguish between the two.

 

Best Colors for Color Blind Presentations

High Contrast Combinations:

  • Black text on a white background or vice versa.
  • Dark blue on a light yellow background.
  • Dark green on a light pink background.

Utilize Universal Colors:

  • Blue is generally well-perceived by most individuals, making it a safe choice for text, headers, and accents.
  • Yellow color can highlight important information as it’s distinct from the most common color blindness deficiencies.

Pairing Colors:

  • Using color-coded data, ensure that the colors chosen are distinguishable by using high-contrast combinations.

Avoid Red-Green Pairings:

  • Avoid pairing red and green together, as these colors are challenging for red-green color blind individuals.

 

How do you design charts using a color-blind-friendly palette?

You should plan your color scheme in advance, and be aware of the best colors for color-blind presentations. This will help you avoid making your infographics or charts inaccessible for color-blind users.

1-Avoid color combinations for color-blind users:

  • Red and green
  • Green and brown
  • Blue & green
  • Blue and gray
  • Blue and purple
  • Green and gray
  • Green and black

You can adjust the colors so that one color is extremely dark and the other very light. This will allow you to create contrast.

2-Adding shapes

To outline different content types, you need to use different sizes and shapes. Color blind people reported difficulty seeing the differences between the two colors because they blur together. They did however note that high contrast and thick lines could help them distinguish. To ensure that your content is easily readable, increase the contrast and thicken lines to at least 2px.

3-Design your color scheme

It is strongly recommended that you use a consistent color scheme for all content if you are creating a color palette that appeals to color-blind audiences. It is important to keep your brand and project colors consistent. You should choose the right colors to reflect your brand and use them throughout your visuals. You don’t have to compromise the aesthetics of your brand by designing a colorblind-friendly palette.

4-Add symbols and text labels

Make text labels descriptive and prominent by using them. These labels will help users with normal vision to lessen the strain on their eyes.

Icons and symbols are great for making your designs more accessible. They visually punctuate a message, without having to rely on color.

Last, but not least: Always underline hyperlinks and never underline regular text. To make your content easier to read, hyperlinks should be the same color as the text and highlighted. Users with similar vision will notice these hyperlinks faster.

5-Different shapes, patterns, textures, and labels are possible

Consider the best color blind friendly palette PowerPoint. It is best to use one color to distinguish the data series so that everyone can understand your plot. This design ensures that all colorblind readers can understand the plotted data regardless of their particular circumstances. The chart will remain clear even if printed in black and white (no gray shades).

6-Use high-contrast colors

Most people who are colorblind don’t have to worry about contrast. To make the contrast stronger, you can change the hues of your colors. You can play with different hues and levels of saturation.

Some alternative two-tone color mixtures include green/magenta, yellow/blue, and red/cyan. Even better, only use multiple colors when necessary.

What color is easiest for colorblind people?

Note that blue is the color most examined for normal people and readers with red-/green-blindness (the most common type of colorblindness). “Blue is the safest shade.” Choose blue if you want red- and green-blind readers to perceive color as you do.
