Color Temperature*(10.0)*


The LG 55LE5500 is great at maintaining a consistent color temperature. As you can see from the chart below, the color temperature warms and cools slightly over the run of the signal range, but it rarely strays outside the limits of the imperceptibility. (More on how we test Color Temperature.)

RGB Curves*(8.87)*


The LG 55LE5500's color performance, like most of the LG's we've reviewed, was very, very strong. The red, green, and blue channels are quite smooth. The shadow details are a little flat, but that smooth, gradual slope you see in the chart below is exactly what you want to see. We did notice a slight loss of detail in the extreme highlights, indicated by that flat bit in the upper-right edge of the lines. (More on how we test RGB Curves.)

Color Gamut*(4.57)*


The LG 55LE5500 matched up fairly well with the rec. 709 color curve, except for the white point (those circles in the middle of the triangle). The white point is generally much bluer than ideal, which cost it a better score in this test. The green point is also undersaturated, but the red and blue points are spot-on. (More on how we test Color Gamut.)
