rgba0006

rgba0006 is a designation used in some digital graphics discussions to refer to a variant of the RGBA color model. It is not an official standard but appears in experimental repositories and educational discussions about color encoding.

Origin and naming: The rgba prefix denotes red, green, blue, and alpha channels. The suffix 0006 is a version-like tag used by a subset of communities to indicate a particular variant with modified alpha handling.

Technical characteristics: In rgba0006, the RGB channels are treated as standard 8-bit values. The alpha channel is typically quantized or constrained to a smaller precision to enable compact storage or faster blending. The variant is discussed in terms of interoperability caveats, because its nonstandard alpha behavior may not be supported by all tools.

Applications and usage: rgba0006 is of interest mainly in experiments, shader demos, and color-quantization studies. It is used to illustrate how changes to alpha precision affect compositing, artifacts, and file size. It is not recommended for production workflows that require full compatibility with mainstream color pipelines.
