Module color 

Color processing primitives.

This module provides functions for color correction in the raw processing pipeline:

• White balance correction
• Color matrix application (camera RGB to sRGB)
• Gamma correction

All functions operate on 16-bit RGB data in the range [0, 65535].

Structs

GammaLut

Pre-computed gamma correction lookup table.

Functions

apply_color_matrix

Apply a 3x3 color matrix to an RGB image.

apply_gamma

Apply gamma correction to an RGB image.

apply_white_balance

Apply white balance to an RGB image.

apply_white_balance_raw

Apply white balance to a raw Bayer CFA image.

clamp_u16

Clamp a floating-point value to the u16 range [0, 65535].
