Now, for the first time, a solution for color blind people to enjoy increased color perception in full color movies and sports on the HDTV in their home. (Plus – a new opportunity for Systems Integrators)
The Inventor & Engineer behind the Murideo-Prisma has a son who is color blind. An expert in color science who designed several products over the past twenty years for several video-centric companies, decided to find a mathematical solution to the problem. With an extreme depth of knowledge and a collection of color math developed through the years the resulting technology is now available in the Murido-Prisma video processor. The “Prisma” was originally developed for studios, integrators and videophiles for enhancing the picture quality in digital displays to match industry requirements and specifications for production, post production and reproduction of movies and digital video. The key components of hardware do not need modification – the firmware – or instructions/code is the only change needed to gain access to the new functionality today.

Simulated Correction (For Non-Colorblind)
Background on Color Blindness - Color blindness (or, more accurately, color vision deficiency) is an inherited condition that affects males more frequently than females. According to Prevent Blindness America, an estimated 8 percent of males and less than 1 percent of females have color vision problems.
Red-green color deficiency is the most common form of color blindness.
Much more rarely, a person may inherit a trait that reduces the ability to see blue and yellow hues. This blue-yellow color deficiency usually affects men and women equally.
Normal vision vs. colorblind vision. The term "color blindness" is misleading, because most "colorblind" people see colors, but their color perception is limited and inaccurate. The most common form of color vision deficiency causes inaccurate perception of the colors red and green, making it easy to confuse them.
Contrary to popular belief, it is rare for a color blind person to see only in shades of gray.
Most people who are considered "color blind" can see colors, but certain colors appear washed out and are easily confused with other colors, depending on the type of color vision deficiency they have.
What Causes Color Blindness?
Color blindness occurs when light-sensitive cells in the retina fail to respond appropriately to variations in wavelengths of light that enable people to see an array of colors.
Photo-receptors in the retina are called rods and cones. Rods are more plentiful (there are approximately 100 million rods in the human retina) and they are more sensitive to light, but rods are incapable of perceiving color.
The 6 to 7 million cones in the human retina are responsible for color vision, and these photo-receptors are concentrated in the central zone of the retina called the macula. The center of the macula is called the fovea, and this tiny (0.3 mm diameter) area contains the highest concentration of cones in the retina and is responsible for our most acute color vision. Inherited forms of color blindness often are related to deficiencies in certain types of cones or outright absence of these cones.
The three types of cones translate into tree main types of colorblindness:
In each of these cases, the affected cones can either be mutated or defective. A mutated cone causes a slight shift and a defective cone causes bigger shift in the color perception.

The three types of cones translate into tree main types of colorblindness:
- Deuteran (green),
- Protan (red) and
- Tritan (blue).
In each of these cases, the affected cones can either be mutated or defective. A mutated cone causes a slight shift and a defective cone causes bigger shift in the color perception.
Solution - New 3D LUT files are now available for the Murideo Prisma in firmware revision prisma-v1.06-1407.mcu and is available below to address all three:
protan-sim – simulation file for protan
protan-PrismaSight – compensation file for protan
deutran-sim – simulation file for protan
deutran-PrismaSight – compensation file for deutran
tritan-sim – simulation file for tritan
tritan-PrismaSight – compensation file for tritan
Conclusion & moving forward – All of you who are systems integrators and are reading this have color blind customers – 8% of the male population has some issue with color vision. Now, you can address it – and not with a lot of additional test tools and software required by the core users of this product.
We are modifying and have inventory of units pre-installed with the new firmware to address color blindness – these are available to ship today – but supplies are limited and the next manufacturing run is scheduled for February – so act fact to lock in your Prisma.

So...What Does It Do Exactly?
- Mathematically compensates for three main types of color vision deficiencies - Protanopia, Deuteranopia, and Tritanopia.
- Hardware correction based so it works with all HDMI video sources - DVD, BluRay, Cable and Satellite boxes, Game Consoles (PS3, XBox)
- Allows the person with a color vision deficiency to see picture detail that was previously not visible
- Simple push button operation to select compensation mode (pass-through, protanopia, deuteranopia, triatnopia)
- Uses scientific algorithm to compensate for color vision deficiencies.
- Works with all display and projector technologies - Plasma, LCD, LED, DLP, LCos., OLED, Projectors and Computer Monitors
- Compensates for color vision deficiency by shifting indistinguishable colors to visible colors.
- Seven preset tables available for easy operation:
- Pass thru (no change)
- Simulate Protanopia, Deutranopia, Tritanopia
- Compensate for Protanopia, Deutranopia, Tritanopia
- Corrects all HDMI video - independent of video source and display technology.
