Color Adaptive Graphics

A technique for automatically adjusting the colours in graphical content so that objects maintain similar colour contrast relative to their reference background colours, regardless of the viewing context. Unlike recolouring approaches that focus on preserving the author's intended colour relationships, colour adaptive graphics adjusts colours based on the principle of simultaneous colour contrast — the phenomenon where the perceived colour of an object changes depending on its surrounding colours. This approach has been applied to maps and data visualisations where overlaid information needs to remain legible against varying background colours.
