Color Balance Tool

The Color Balance Tool provides deterministic, per-region color adjustments for RGB swatches and images. Users supply base colors as hex swatches or image data and configure distinct shifts for shadows, midtones, and highlights. The system operates in the sRGB color space with a D65-like white point and outputs corrected color values or a revised swatch set that can feed downstream design and asset pipelines. It is designed for photographers, digital designers, and prepress teams that require repeatable balance across multiple assets.
Core computation uses a luminance-based routing: each color is converted to RGB, luminance Y is computed, then the corresponding regional delta is applied to each channel. After applying the shifts, values are clamped to 0–255. Optional gamma correction can preserve perceptual brightness when performing larger shifts. When image data is provided, the same regional balance logic can be applied per pixel to generate a preview image and a pixel-mapped output.
Outputs include corrected hex swatches and an optional export image (PNG) for immediate review. The tool supports batch processing of many swatches and can integrate into automated color workflows where branding requires consistent color balance across campaigns. It is not a full retouching tool; it focuses on global color shifts that respond predictably across a palette.
Because the tool relies on simple offsets rather than AI-based suggestions, it favors predictability and auditability. It is well suited for establishing a canonical tonal bias or correcting a color cast introduced during capture, enabling faster handoffs between creative, production, and QA teams.
