Presentations for the Color Blind

Ever wondered how the content you produce e.g., PowerPoint presentations, would appear to a color-blind person?

Early advice recommended using the Grayscale filter (PowerPoint> View> Grayscale) within PowerPoint. As we switch to monochrome, we can quickly tell if the visuals make sense. But then learned that it’s not all black and white. More than 99% of all colorblind people can see color. 

Recently chanced upon this amazing tool called Color Oracle that “takes the guesswork out of designing for color blindness by showing you in real-time what people with common color vision impairments will see.” It’s a free color blindness simulator available for download, for Windows, Mac, and Linux.

Though there are some great online simulators like the one from, Color Oracle does not require you to upload an image/ pdf. It applies a full-screen color filter. So irrespective of what software you are working on (PowerPoint or graphical UI), you get to see immediate results.
