16-color bitmap, 256-color, 24-Bit Bitmap

We often say that Windows 95/98 is in a 16 or 256 color state, which means the maximum number of colors displayed on the screen.

You can see that it is normal to display black-and-white text or simple color lines in 16 colors, but if we want to see more than 16 colors, you have to use 256 or more colors. That is to say, you need to set the display mode to a high color state.

For each pixel on the screen, 256 colors are represented by 8-bit binary numbers, that is, the power of 2. Therefore, we also call a 256-color image as an 8-Bit Bitmap; if the color of each pixel is represented by a 16-bit binary number, we call it a 16-Bit Bitmap, which can express the 16 power of 2, that is, 65536 colors. There is also a 24-bit color map, it can express 16,777,216 colors.

Although the 24-Bit Bitmap cannot express all the colors of nature, it can be used as a false color for our eyes, so we call it true color. If an image is of 256 colors, the effect is the same in true color as in 256 colors. However, if it is of true color, then the effect will be far worse in 256 colors. Similarly, a 256-color image may become very poor in 16 colors.

Some early display cards can only display up to 256 colors. It is obvious that this is not worth the candle. However, as technology advances, storage capacity, and speed increase, our display cards can now display 24-bit real color, therefore, multimedia discs are gradually being created in real color. If you do not know the color of your computer, right-click the desktop, select "properties", and then select "Settings ", you can view and modify the color settings in the "color" column. If you want to change the display color, you can select the appropriate color status here, for example, select the enhancement color (24-bit), and then click "OK ".
