我正在读一本书,但我不确定这是一个错误还是我误解了引文。上面写着……

Nowadays every PC you can buy has hardware that can render images with at least 16.7 million individual colors. Rather than have an array with thousands of color entries, the images instead contain explicit color values for each pixel. A 24-bit display, of course, uses 24 bits, or 3 bytes per pixel, for color information. This gives 1 byte, or 256 distinct values each, for red, green, and blue. This is generally called true color, because 256^3 (16.7 million)

他说 1 个字节等于 256 个不同的值。 1 字节 = 8 位。 8^2 位 = 64 种不同的颜色对吗??这不适合我。我知道这可能很容易理解,但我不明白。
