Accessibility - Colour Blindness
Hi Heroes,
I'm working on a Storyline project that includes accessibility considerations. I'm very interested in your design experiences of visual impairment and colour-blindness. I'd like to incl...
Hi Andreas,
One design rule says that for accessibility, you should not let color be the only way that information is conveyed. So, you could use color like in your sliders, but what about also adding numbers or letters with each distinct color. That way, someone with color blindness could more easily determine which box is which. The problem is that someone with color blindness might see two or more of your colored slider boxes as looking identical. With numbers in each box, it would at least distinguish the individual boxes by something other than color. Even better might be to put the name of the color in the boxes.
In case you didn't know, Adobe Color is a free website that allows you to check your color palette to see if it is safe for those with color blindness. Simply enter the colors you are using, such as the colors on your slider, and you will see how people with different color blindness types really view the colors. You can tell if your colors are not distinct enough for someone with color blindness to be able to tell the difference.
