Color Accuracy

Accurate RGB curves. Color temperature jogs towards warm in darker scenes.

The Samsung UN55C7000 didn’t have the best color temperature. In our test, we saw that the dark end of things trends towards a bit of a warm look. Not great, but a pretty cut and dry case of not great.

One other issue is that, without the contrast at the setting it’s at, we noticed some of the whites were noticeably warmer than the peak white, so much so that they really looked kind of pink. Stick to our calibration, however, and it should mitigate the effect. More on how we test color temperature.

For the most part, the UN55C7000 had some great RGB performance. It has a good slope to its curves, meaning the colors transition from dark to light evenly. This is ideal, because a smooth transition like this means you aren’t losing many fine details. Towards the bright end of the spectrum, however, the lines do get a bit bumpy, meaning adjacent colors will either be too different in shade or not different enough to distinguish much of a difference between the two. More on how we test RGB curves.

Below we’ve graphed the red, green, and blue curves as gradients. Ideally these gradients should show a seamless transition from highest to lowest intensity and show the entirety of the spectrum. Look for bands of color or bright to black, which indicate a loss of detail, and look for where the color bottoms out, i.e., when it just flattens out to black. The only spot that should be true black is the very, very end, which is rarely the case.

TV’s color gamut was a bit off. We measured the green as being a bit oversaturaged, the red was slightly oversaturated and shifted towards blue, and the blue was pushed towards red and also oversaturated. More on how we test peak color gamut.
