8BitSRGBFarbraum

8BitSRGBFarbraum refers to the colour space obtained when standard sRGB is encoded with 8 bits per channel, yielding a 24-bit color representation (8 bits for red, green, and blue). This configuration uses the sRGB primaries and a white point of D65, matching the widely adopted sRGB standard. The colour data is nonlinear due to the sRGB transfer function, which approximates a gamma of 2.2 to align with human perception.

In practice, 8-bit per channel enables 16,777,216 possible colours. While this depth is sufficient for most consumer applications, it can introduce banding in gradients and smooth transitions, especially in low-light or high-contrast areas. Dithering is commonly employed to reduce visible quantization artefacts.

Applications of the 8BitSRGBFarbraum include web graphics, digital photography workflows, and consumer displays where compatibility and standardization are priorities. It is largely device-dependent unless proper colour management is used; assigning an appropriate ICC profile helps map image data to device primaries and maintain consistent colour across displays and software. The space is not linear; processing such data typically involves converting to a linear light space for mathematical operations, then re-encoding to sRGB for display or storage.

Relation to broader concepts: 8BitSRGBFarbraum is distinct from linear RGB and from wider gamuts used in HDR workflows. It remains a foundational colour space for many standard imaging pipelines and formats, including JPEG and PNG, where 8-bit sRGB is a common default.
