Converting Colors in JavaScript at 6 Billion Operations Per Second

Converting colors in JavaScript at 6B operations per second

I built @colordx/gpu to handle real-time color rendering by shifting heavy calculations from the CPU to the GPU. While my CPU-based library handles single conversions efficiently, rendering millions of pixels requires parallel processing. By sending mathematical rules instead of raw data to the fragment shader, I achieved over 6 billion color conversions per second on an Apple M4, outperforming the CPU by 400 times.
