Score: 5.7/10 (Innovation: 7, Technical: 6, Documentation: 3, Utility: 4)

This project demonstrates a technique to render images brighter than standard white by exploiting Rec.2100 PQ (Perceptual Quantization) color profiles, enabling a form of HDR-like brightness in web images. It is interesting for its clever abuse of video color standards to achieve a visual effect not normally possible with standard image formats. The utility is niche, targetting developers experimenting with HDR or advanced rendering.

Target audience: frontend devs, graphics programmers
