Ok, let me get to the issues that were mentioned previously, but
Where I stated in the advantages that you get more colors, it is that your resolution is
actually separate from the bits per pixel (bpp), but when someone is speaking about
resolution, they're usually including bpp. bpp refers to the number of bits used to
describe the color of a single pixel on-screen. Usually I'm bad at
analogies, but I think I made this one fairly clear.
Let's say I wanted to describe my appearance to you.
Let's assume I'm running 1 bpp. That means I am limited to one word to describe myself.
Instead of 1 word, a computer would have one bit, either on or off. That means that it can
display a black pixel (off/0) or a white pixel (on/1).
Now let's move to 2 bpp.
Me: MALE, CAUCASIAN
Computer: four colors to choose from 00, 01, 10, 11.
In case this doesn't make sense, computers are binary (base 2). They deal with 1's and
0's, where humans normally deal with a deci system (base 10). In base 10, your
placeholders are 1's, 10's, 100's, 1000's, 10,000's etc.. In base 2, they are 1's, 2's,
4's, 8's, 16's, 32's, 64's, 128's, 256's, 512's, 1024's etc.
Because computers are base 2, the next step in my analogy is 4 bpp.
Me: MALE, CAUCASIAN, BLONDE, BLUE-EYED
Computer: 16 choices, 0000, 0001, 0010, 0100, 1000, 1001, 1010, 1100, 1101, 1110, 0110,
1111, 0011, 0111, 0101, 1011
Do you see the pattern yet?
So you can see that the higher your bpp, generally the better pictures will look. The
computer can more accurately represent the true color in the picture because it has more
colors to choose from, hence less dithering.
