Due to the versatility of the term "indicated" is a "indexed level" by no means self-explanatory. Indexed colors are sometimes very useful in Photoshop and other graphics editing programs, like GIMP. This means a level is indexed"":
- In Photoshop and other graphics Tools you can index colors, that is, save them to a "color table" or "color palette" and from here retrieve.
- Use exactly four colors to choose, however, you could save the graphic with 24-Bit.
- Efficient, space-saving, however, is to encode this image with 2 Bits, for example, as a 2-Bit GIF or PNG.
- So that the Computer knows which bit string should correspond to which color, is stored, a color palette, where the colors are "indexed".
- Only in the case of Standard pallets, such as 1-Bit Black-and-White and grayscale 8-Bit, must not be stored color tables.
- In an indexed level, the number of allowed colors through the color table is limited. Effects like transparency, Blur and color filters work, sometimes not.
- Indexing can be useful, so that you only work with the exact colors that are included in your target format is actually.
