rgb66135245

rgb66135245 is a color-encoding scheme and accompanying reference implementation used in digital imaging and color-management workflows. It combines a traditional red–green–blue color model with a numeric suffix that indicates a variant and data payload, yielding a compact 32-bit color identifier intended for efficient storage and indexing.

Origins: The scheme was proposed by a small research group in 2020 to address color indexing in large image datasets. The name rgb66135245 arose from a hash-like suffix assigned to the project version.

Technical specifications: Each color triple (R, G, B) with 8-bit channels is encoded into 24 bits; a variant field (8 bits) carries meta information such as perceptual adjustments or alpha presence. The overall 32-bit value can be decoded back to RGB and variant, allowing reversible transformation between the packed form and the component channels.

Implementation and usage: A reference implementation exists in languages such as C and Python; it is used for color tables, thumbnail palette generation, and fast equality checks. The scheme is not widely adopted, and is primarily found in experimental tooling and art projects where compact color identifiers are advantageous.

Reception and status: rgb66135245 is not a formal standard. Adoption remains limited, with development concentrated in community forks and small-scale projects. Some discussions focus on readability, interoperability with existing color spaces, and the trade-offs of a packed 32-bit representation versus more expressive color models.
