1-bit format. A pixel of the texture can assume only 2
values. It takes up less memory
A2
(256x256)
16kB
2-bit format. A pixel of the texture can assume 4 values.
A4
(256x256)
32kB
4-bit format. A pixel of the texture can assume 16 values.

64kB
An 8-bit colour format with an alpha channel. The texture is
quantized to 256 unique colours. This format is suitable for
coloured textures (e.g. a company logo). It uses little
memory, however, it displays a low rendering efficiency
and results in a visible quality deterioration in the case of
tonal transitions
RGB 565
(256x256)
128kB
A 16-bit colour format without an alpha channel. It has a
very good quality and rendering efficiency. A downside of
this format is that it uses twice the memory of an indexed
format

(256x256)
128kB
A 16-bit colour format with an alpha channel. It has a very
good quality and rendering efficiency. A downside of this
