Color Palette Reference Chart - Web Design & Accessibility Guide #1199826 (License: Personal Use)

This image displays a 3-row by 10-column grid of solid-color blocks, illustrating a spectrum from black through deep reds, oranges, yellows, and bright greens. The arrangement highlights luminance variation and color harmony, useful for evaluating contrast ratios and visual hierarchy in digital interfaces. Each block is uniform in size, enabling precise comparison of adjacent and distant hues.

Used on web design resource pages, accessibility guidelines, or developer documentation to demonstrate color selection, contrast compliance (e.g., WCAG), and palette planning. Matches user intent for designers seeking reference swatches or testing color readability.
