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-blindness.com, 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.
