Colour in the Real World
summary
Shows concrete takeaways: historical pigments like Tyrian purple require 300 lb of shellfish for 1 oz of dye, and lead white reveals forgeries under X‑rays; about 4% of people have color-deficiency. Demonstrates practical tooling and techniques — Sass functions mix and complement, SVG styling, Photoshop and Color Oracle for simulation, plus Chrome/Firefox add‑ons — with live demos (the dress, layered mountains, and sails) that reveal how color constancy, atmospheric perspective and accessibility actually behave and how the code changes their appearance.
