What is the maximum length of a GIF?

Why do Gifs only have 256 colors?
When you save images to GIF the colors will be indexed. A typical GIF can only contain 256 colors. Each pixel will be converted to one of these colors from the index. You can enable dithering, this will use an algorithm that ‘shuffles’ some pixels and colors for a better result.
What file format supports only 256 colors and can be a GIF substitute?
PNG

An animated GIF illustrating a technique for displaying more than the typical limit of 256 colors Although GIF is almost never used for true color images, it is possible to do so.

What are true-color GIFs?
True-color GIFs are a hack that uses the animated GIF format, puts a 256 color square in each frame, offset from all previous frames, makes each frame not disappear when the next frame appears, and loops only once. Few programs other than web browsers display such images correctly. The files are very large as a result and not suitable for web use.
What are the disadvantages of using GIFs?
Due to the reduced number of colors in the image, there are display issues. GIF is palette-based: the colors used in an image (a frame) in the file have their RGB values defined in a palette table that can hold up to 256 entries, and the data for the image refer to the colors by their indices (0–255) in the palette table.
