I built an app that creates repeating patterns from an image (PNG or SVG). Users can change the input image size, pick a background color, and export the final pattern as a PNG or SVG.
Created an accessibility contrast grid that uses either WCAG or APCA. You can bulk load your palette and reorder the grid in order of conformance level, background color, or text color.
