How To Choose Color Blindness Palette? Accessibility Tips

Choosing the right color palette is crucial for ensuring that your digital product, website, or application is accessible to everyone, including those with color blindness. Color blindness, also known as color vision deficiency, affects approximately 8% of males and 0.5% of females worldwide. It’s essential to select a color palette that is not only visually appealing but also accessible to users with color blindness.

Understanding Color Blindness

Before we dive into choosing a color blindness-friendly palette, let’s understand the different types of color blindness. The most common types are:

• Red-green color blindness: This is the most common type, where individuals have difficulty distinguishing between red and green colors.
• Blue-yellow color blindness: This type is less common, where individuals have difficulty distinguishing between blue and yellow colors.
• Total color blindness: This is a rare type, where individuals see the world in shades of gray only.

Color Blindness Palette Principles

When choosing a color palette, follow these principles to ensure accessibility for users with color blindness:

1. Contrast: Use high contrast between colors to help users with color blindness distinguish between different elements on the screen.
2. Saturation: Avoid using highly saturated colors, as they can be difficult for users with color blindness to distinguish.
3. Hue: Choose colors that are far apart in hue to help users with color blindness distinguish between them.
4. Avoid similar colors: Avoid using similar colors, such as blue and purple, which can be difficult for users with color blindness to distinguish.

Color Blindness-Friendly Color Palettes

Here are some color blindness-friendly palettes that you can use:

1. Monochromatic palette: Use different shades of the same color to create a monochromatic palette. This palette is easy to read and understand, even for users with color blindness.
2. Complementary palette: Use colors that are opposite each other on the color wheel, such as blue and orange. This palette creates high contrast and is easy to read.
3. Analogous palette: Use colors that are next to each other on the color wheel, such as blue, green, and yellow. This palette creates a harmonious and accessible color scheme.
