The Accessible Perceptual Contrast Algorithm

SoftContrast is an anti-halation reading palette generator leveraging the Accessible Perceptual Contrast Algorithm (APCA) and OKLCH color science to reduce visual degradation (irradiation blur, ghosting) for low-vision and astigmatic readers.

This preview area demonstrates the selected color palette in real-time. Notice how the text contrast changes smoothly.
