When it comes to cover design and graphics the last thing most DIY authors will think to consider is color blindness. With almost 10% of the world having some form of color blindness, an amount nearly equal to the population of the United States, this affliction is something everyone should consider when it comes to graphic design. If you suffer from color blindness what comes next can help you create great designs too.
Types of Color Blindness
It’s good to know the different types of color blindness in order to appreciate what your colorblind viewers will be seeing in your designs.
Color blindness doesn’t mean that you only see in black and white; that is one form of color blindness, although it is very rare.
Color blindness is most common in reds and greens and then less commonly in blues and yellows. This is where color blindness relates to the difficulty in distinguishing between certain shades of certain colors. Some colors tend to blend into one another.
Some Rules for Designing
- Avoid the following color combinations: these color combinations are difficult for people with colorblindness: Green & Red; Green & Brown; Blue & Purple; Green & Blue; Light Green & Yellow; Blue & Grey; Green & Grey; Green & Black.
- Make it monochrome: Take the design you’ve made in your design platform and switch it to grayscale mode. When you are seeing it in only black and white and shades of gray, you can easily spot where colors may blend together for someone with colorblindness.
- Use high contrast: High contrast is something to consider in design because people affected by colorblindness can usually distinguish between colors when there is a high degree of contrast.
- Colors won’t signal emotion: color for most people symbols mood and evokes emotion, but it won’t for people who are color blind. Make sure you are adding good design elements beyond color to relate mood or stir emotion.
- Use texture instead: in maps and infographics you can try using texture in addition to color to differentiate between objects.
For designers’ it will help to see what a person who is colorblind might be seeing when they’re viewing their designs. Some of these links are also helpful to designers who suffer from colorblindness. If you are wanting to get it right, here are some links to help you do just that.
- Colorblind Web Page Filter: here you can just type in a URL and choose which type of colorblind filter you’d like to apply. Now you can see your design in that form of colorblindness.
- Coblis: another great colorblind simulation application.
- Color Laboratory: this will help you choose which colors will work well together for a colorblind viewer.
- Color Oracle: color blindness simulation for Windows, Mac and Linux users.
- Color contrast visualizer: this will help any designer choose good color combinations.
Design Help for the Colorblind
There is no reason why you can’t create great designs even if you’re colorblind. All you need to get started are some great color pallets. Below is a link to a site that will help you whether you are colorblind or not, to create pallets that will work in every single design you create.
Coolers: this sight will help you create beautiful color pallets that you can then use in your graphic design software.
Are You Color Blind?
Many people have some form of color blindness and aren’t aware of it. Here’s a link to a test to find out if color blindness affects you:
I want to thank my editor for reminding me that I hadn’t included this section in my cover design book! He’s the best! I recommend Dennis to all of my clients:
