Color Temperature*(8.74)*


The Panasonic TC-P42U2 had a bit of a struggle with maintaining a consistent color temperature, but we've certainly seen a lot worse. As you can see from the chart below, there was a tendency to warm the whites as it moved through the signal intensity scale. It strayed only occasionally outside the bounds of the 'perceptible error limit.' (More on how we test Color Temperature.)

RGB Curves*(6.58)*


The color curves below are certainly far from smooth, and they don't always move in tandem – the green and blue channels are clearly more closely interlinked. Each of those little hiccups in the line indicates a portion of the spectrum where you might expect to see color banding. You can see some of this effect approximated in the color strips that appear below this chart. Overall, the Panasonic TC-P42U2 was not a stellar performer. (More on how we test RGB Curves.)

Color Gamut*(4.63)*


The Panasonic TC-P42U2 does not match up all that well to the rec. 709 color standard. A look at the chart below tells you that the green point is quite a bit off the mark. The red is a little better, as is the blue. However, the oversaturation of the green cost the Panasonic TC-P42U2 a lot of points in this test. ( More on how we test Color Gamut.)
