Shows concrete techniques: apply CSS blend modes and filters plus SVG FEColorMatrix to recreate duotone and Instagram‑style filters, simplify things like knockout text, and drive live color swaps for e‑commerce. Case studies include a visual diff tool (Diffy) and CSS Graham. Browser support is mixed (Edge/IE missing, Safari partial) and progressive enhancement is required. Measured gains: removing color often saves ~17–23% of image size (examples 62 KB and 189 KB); profiling finds only fractional paint cost under heavy CPU slowdowns.
