Not if you have had a technician come out to your house from Joe Kane's Imaging Science Foundation and calibrate your television set to the exact standards of the NTSC system. Then you will see the most accurate color possible, up to the limit of the ability of your particular set.
When and if I ever get my dlp front projector and build my home theater room, you can bet that baby will be calibrated. I think Joe Kane has done a great service to anyone that likes to watch a television and wants it to look good. He has been the main person in trying to educate the buying public about how bad the sets look today, because of the competition in the industry. He even produced the Video Essentials dvd that not only is a great source of information to educate yourself, but it gives the test patterns necessary to properly adjust your set.
Joe helps with the problem that some joking refer to NTSC as meaning, Never Twice the Same Color. I don't want to get too technical, but some may not be aware that our television system has a set of standards and any thing that is not set exactly to that standard will produce inaccurate color.
In the NTSC system, the color temperature is to be set at exactly 6500 degrees kelvin. Anything other than this, and it results in inaccurate color. Every television manufacturer in the world knows this.
But here is where the problem comes in. It is an absolute fact that to the human eye, looking at 100 color televisions lined up in a store, the human eye will be drawn to the one with the brightest picture. When your eye is drawn to that picture, you will declare that set as the one with the best picture and you will happily purchase that set. It does not matter in the least how inaccurate that color is, your eye will tell you that the brightest one is the best. Every television manufacturer in the world, knows this also.
So, to sell more tvs, here is what has happened. Everyone started at the correct standard. Then one manufacturer raised their color temperature a little above 6500 degrees and started selling more tvs. Lets just say that this first manufacturer was Sony. Well, Toshiba isn't going to stand by and lose sales. So Toshiba raised theirs a little higher than Sony's. Then Sharp came along and raised theirs higher than Toshiba, so Panasonic raised theirs higher than Sharp and Sony raised theirs again. And so on and so on and so on.
It is truly amazing that a new television will display a picture that is even watchable. With every manufacturer knowing that any thing other than 6500 degrees Kelvin, will produce an inaccurate color picture, we have sets that are sold today that are set at the factory with the color temperature at 10,000 to 15,000 degrees and higher.
I even know of one very high end maufacturer that after Joe Kane began educating the public, began to offer their sets with the color temperature at 6500 or at their normal setting. It was up to the choice of the consumer. But most people would choose their normal setting, because they don't even know what they are talking about.
These settings have gotten so high that they can do damage to the tv. The picture tube is so over driven that it will cause it to wear out prematurely. Like your tv wearing out too soon is going to hurt their sales and cause them to stop this practice. Every television maufacturer in the world today, is laughing all the way to the bank.
They know that they are getting way out of hand. Some have begun to put a choice of color tempertures on the controls that are user adjustable. If your set has a choice of temperture settings, choose the one that says warm or low. Do not use the other ones that may be labeled cool or high or medium. Even these lower settings are probably above 6500 degrees, but at least they are closer than the other settings.
Turn your sharpness setting completely off or at least very low. This adds something that is not even in the original signal and is basicly just video noise. It is supposed to increase the contrast. Keep your Brightness control turn to the lower side of the scale and your contrast setting fairly low also.
The best advice that I can give is to get a copy of Video Essentials or one of the other dvds that help you adjust your set with test patterns. Another excellent disc such as this is called Avia. The ultimate advise is to have your set professionally calibrated. And no, most television repairmen are not trained in how to do this.
