“Color Accuracy” is a term that LG used in the technical specifications of its TVs to describe color reproduction. In later models, LG also used the terms “True Color Accuracy” and “True Color Accuracy Pro.”
These terms describe how a TV processes colors and how accurately they are reproduced on the screen. They do not refer to any specific technology but are rather descriptive terms that encompass several image-processing technologies.
What Color Accuracy means
Color accuracy describes how closely the colors displayed by a TV correspond to the intended colors in the original content.
For example, if a video contains a particular shade of red, accurate color reproduction means that the TV displays a similar shade rather than noticeably shifting it toward orange or another color. The same applies to skin tones, blue skies, green vegetation and other colors in an image.
Color reproduction depends on several factors, including the display panel, image processor, calibration and image-processing algorithms.
| LG term | Meaning |
|---|---|
| Color Accuracy | Describes accurate reproduction of colors |
| True Color Accuracy | LG’s later terminology for accurate color reproduction |
| True Color Accuracy Pro | LG’s more advanced color-processing system used on selected models |
| True Color Accuracy Pro (33x33x33) | True Color Accuracy Pro specified with a 33 × 33 × 33 color table |
Color Accuracy vs Color Gamut
Color Accuracy and Color Gamut describe different aspects of color reproduction.
Color gamut defines the range of colors that a display can reproduce. Color accuracy describes how closely those colors match the intended values.
| Characteristic | Meaning |
|---|---|
| Color Gamut | The range of colors a TV can reproduce |
| Wide Color Gamut | A larger range of reproducible colors |
| Color Accuracy | How closely displayed colors match the intended colors |
| High Color Accuracy | More precise reproduction of the intended colors |
A wider color gamut does not automatically mean better color accuracy. A TV can reproduce a large range of colors while still displaying some colors inaccurately.
What is True Color Accuracy Pro?
LG used True Color Accuracy Pro on selected TVs as part of their image-processing system. The technology was associated with LG’s α9 image processor.
LG described the system as using a detailed color table to provide more precise color processing and reduce color distortion.
Some LG models specify the feature as True Color Accuracy Pro (33x33x33). The 33 × 33 × 33 designation refers to the dimensions of the color lookup table used during processing. This gives the system 35,937 combinations for the three color dimensions.
The number does not mean that the TV can display only 35,937 colors. The table is used to process and map colors before they are displayed.
LG used True Color Accuracy Pro on both OLED and some LCD-based TVs, so the term does not identify a particular panel technology.
Why LG used these terms
LG used the terms “Color Accuracy” and “True Color Accuracy” to highlight precise and natural color reproduction in the technical specifications of its TVs. The term “True Color Accuracy Pro” was applied to models with a more advanced implementation of this technology. However, these terms do not actually have units of measurement and cannot be measured. In fact, it could even be said that this is largely a marketing term used by the company to promote its TVs.
These terms were particularly common in LG’s technical specifications in the late 2010s and early 2020s. Therefore, the image feature lists of older models may include the terms “Color Accuracy” or “True Color Accuracy Pro.”
Since then, LG has changed the terminology used in its technical specifications. In newer TVs, the term “Color Accuracy” may no longer appear in the technical specifications.
