Indexed color is a technique used in computer graphics to represent images with a limited number of colors. Unlike true color, which uses millions of colors, indexed color uses a palette of just a few colors. This technique is often used to reduce file size and the Performance to optimize, especially for images that are used on the Internet. This index value corresponds to a specific color in the palette. By limiting the number of colors used, indexed color can produce visually appealing images while reducing memory requirements.

Put your knowledge to the test

Take a technical terminology quiz

Now that you have a basic understanding of indexed color, it's time to put your knowledge to the test! Take this quiz to see how much you've learned.

1. What is indexed color?

Indexed color is a technique used in computer graphics to represent images with a limited number of colors. This involves creating a color palette that contains a fixed set of colors that can be used in an image. Each pixel The image is then assigned an index value that corresponds to a specific color in the palette. This allows for efficient storage and display of images, especially in situations where storage or bandwidth is limited.

2. Why is indexed color widely used on the web?

Indexed colors are used on the web to reduce file size and optimize performance. Limiting the number of colors used in an image can significantly reduce file size, resulting in faster loading times for web pages. Additionally, indexed color allows for better compression of images because the limited color palette can be encoded more efficiently. This is especially important for users with slower internet connections or limited data plans, as it helps minimize data usage without compromising visual quality.

3. How does indexed color work?

Indexed colors store an index value for each pixel in an image that corresponds to a specific color in the palette. When an image is saved in indexed color mode, the software that created or edited the image creates a color palette based on the colors present in the image. The palette can contain a few to several hundred colors depending on the desired level of color fidelity. Each pixel of the image is then assigned an index value that corresponds to a color from the palette. This index value is stored in the image file along with the color palette. When the image is displayed, the software or browser reads the index value for each pixel and finds the corresponding color in the palette so that the correct colors are displayed.

Now that you have a deeper understanding of indexed colors and their applications, you can appreciate their importance in computer graphics and web design. By using indexed colors, you can create visually appealing images while keeping file sizes small and optimizing performance. Whether you're a web developer or a graphic designer, indexed colors are a valuable tool in your arsenal.

Understanding indexed color images

The science behind indexed color images

Indexed color images are created by assigning each pixel a unique color index that corresponds to a specific color in the palette. This color index is stored in the image file, along with the corresponding color palette.

One of the advantages of indexed color images is the smaller file size. Because only a limited number of colors are used, indexed color images can be much smaller than their true color counterparts. This makes them ideal for use on the internet where fast loading times are important.

Demystifying technical terminology
