Are You Ready to See More Intense Colors on Your TV or Computer Screen?

How It Works

​

ColorblindTV runs on an ordinary Windows PC, such as a small, inexpensive mini PC or a laptop, connected to your TV or monitor with an HDMI cable. You watch Netflix, YouTube, Prime Video, Xfinity and other services in the PC’s web browser, and ColorblindTV adjusts the colors of everything on the screen in real time before the picture reaches your display.

​

The strength of the color adjustment can be tuned to match each viewer’s needs using a small on-screen control panel, operated from a keyboard, mouse or handheld TV-style remote. A built-in color test, using dot-pattern plates similar to those used to test color vision, helps each viewer find the setting that works best for them, and that setting is remembered for next time.

ColorblindTV

Video screens create colors by varying the intensity of red, green, and blue light at each pixel.

​

Since people with red-green color blindness have difficulty detecting differences between the amount of red and green in a color, ColorblindTV uses a targeted approach that directly magnifies this difference.

​

ColorblindTV examines the red and green values of each pixel and calculates the difference between them. A percentage of this difference is then added to whichever value is larger and subtracted from whichever is smaller.

​

Equally important, a color with equal amounts of red and green is left unchanged, since there is no red-green difference for someone with color blindness to have trouble seeing.

​

ColorblindTV also applies a separate adjustment to the blue component of each pixel, complementing the primary red-green enhancement by further increasing the saturation and vividness of colors.

​

As a result, ColorblindTV selectively increases the differences among color components that help distinguish colors from one another. Its primary purpose is to magnify red-green differences that are difficult for people with red-green color vision deficiencies to detect.
