@tracychen The human eye can identify around 10 million unique colors, so it stands to reason that a display with 256^3 = 16.7 million color values might be sufficient for the human eye.
The truth, however, is that there are displays that go beyond 8-bits per color channel. For example, UHD (ultra-high definition) TVs support the ability to display 10-bit color values. Of course, you need to provide images with 10 bits per color to take advantage of this feature.
Just Curious, why there are 256 possible values?
