While I have not used the Celerity optical HDMI cable, I can predict that you will get at least 5 responses pointing out that an HDMI cable cannot, under any circumstances, in any part of this Universe, cause colors to be "a bit washed out". The cable transmits bits in the form of an electrical signal. Change the bits and you get garbage, not washed out colors. The only way to get a uniform washed out color set would be either to 1) convert to analog (don't think the cable can do this) and modify the voltages and then convert back to digital or 2) have a digital processor work on each pixel value and lower the appropriate color bits (don't think there is any processor in the cable that can do this). Can you think of any other method for a cable to provide a color shift?
And, as long as the cable is a cerfified High Speed cable, then it will be able to pass the full range of current and planned HDMI signals, which include 4k. Just check to make sure it is a certified High Speed cable (or the equivalent for optical).
