Colorblind Accessibility Manifesto
Before designing a website, or even making a small change to an existing one, ask if your design choices consider the needs of people with color blindness. Changing the button color on your website may seem insignificant, but it could make that website inaccessible to nearly 8% of men and 0.4% of women who have color blindness.
Color Accessibility Workflows ~ Geri Coady
Color is a powerful tool that affords seemingly endless design possibilities, but we often design with only one type of color vision in mind—our own. Make sure that accessibility and aesthetics go hand in hand with every design you create.
Why are hyperlinks blue? ~ Elise Blanchard
I often hear that blue was chosen as the hyperlink color for color contrast. Well, even though the W3C wasn’t created until 1994, and so the standards for which we judge web accessibility weren’t yet defined, if we look at the contrast between black as a text color, and blue as a link color, there is a contrast ratio of 2.3:1, which would not pass as enough color contrast between the blue hyperlink and the black text.
