RGB67

RGB67 refers to a specific color model designation in the RGB color space, where the numerical values represent the intensity levels of red, green, and blue light components. In this system, each color channel is scaled from 0 to 67, rather than the more common 0 to 255 range used in standard RGB (8-bit color depth). This alternative scaling is occasionally employed in niche applications, such as certain video editing software, lighting systems, or specialized graphics tools, where non-standard color depth or compatibility with legacy systems is required.

The RGB67 model divides each color channel into 68 possible values (including 0), resulting in a total of 68³ (approximately 314,432) distinct color combinations. While this is significantly fewer than the 16.7 million colors available in 8-bit RGB (256³), it may be sufficient for applications where high color fidelity is not critical. The reduced range can simplify calculations in some scenarios, particularly in older hardware or software designed for lower precision.

RGB67 is not a widely adopted standard, and most modern systems rely on the more established 8-bit or higher-bit-depth RGB formats. However, it may appear in contexts where backward compatibility or specific technical constraints necessitate its use. Converting between RGB67 and standard RGB involves scaling the values proportionally, multiplying each channel by (255/67) to approximate the equivalent 8-bit color.

This color model is rarely documented in mainstream technical literature, and its usage is largely confined to specialized or historical applications. Developers and designers working with RGB67 must account for the reduced color gamut and potential limitations in color accuracy compared to more widely supported formats.
