Color Gradient Chart - Grayscale & RGB Tonal Progression Visual Reference #2324665 (License: Personal Use)

This image displays four precisely calibrated horizontal color gradients: a neutral grayscale bar, followed by red, green, and blue channels, each transitioning smoothly from maximum saturation (or brightness) to pure black. The gradients are segmented into 20 equal steps, enabling accurate evaluation of luminance and chroma behavior across tonal ranges. Useful for color calibration, UI design, and print workflow validation.

Commonly used in graphic design, web development, and digital imaging resources as a reference for color fidelity, contrast testing, or accessibility compliance (e.g., WCAG luminance checks). Targets users seeking technical color visualization tools.
