For anybody interested in design, whether as a hobby or as a career, it is worth knowing that nearly between 5% and 8% pall men (and about 0.5% of women) have some form of color blindness. That’s an enormous amount of people that will be affected by everyday design choices!
This fact has some really important considerations for a large number of design media. If you ever create an information design piece (a document that is meant to provide useful and informative information so that people can make choices), it is good ethical practice to check your design for color blindness because it makes your design accessible to all persons. Being conscious of colorblindness also ensures that you don’t exclude any potential readers, viewers, or customers.
In the digital era, it is very important to check your websites, especially if color is an important navigational or instructional feature on your website. It’s also a legal consideration if you ever expect to do business with the federal government. Businesses, educational facilities, and other government-supported institutions are required to make visual communications accessible to persons who are color blind.
Of course, color blindness rarely means that a person cannot see any color at all. The most common form of color blindness is red-green, where the two colors are often indistinguishable. You might take a moment to look at your website and look for any shades of green or red. If they are numerous, it might be a red flag to you that your website doesn’t look how you might think it does to many of your viewers.
If you want to check any of your images, designs, or websites for colorblindness, check out these two sites: Vischeck.com and www.checkmycolors.com. If you don’t have any designs, you might just go to these sites and type in URLs to see how the sites you visit often are doing. Hopefully most are doing well. Some may be failing miserably. But all sites that are tied to the government in some had better be doing fantastic!
