To make paint, you basically mix titanium (for whiteness), iron (for reds and ochers), cobalt (for blues), carbon (for binders and blacks), and a splash of silicon or zinc for endurance. It’s like baking a cake, but the cake is ultra-resistant and will stick to your wall for decades.
And if you ever feel overwhelmed by the science, just remember: paint is 20% chemistry, 10% luck, and 70% the satisfaction of watching a fresh coat go on. Plus, you now know that the same element that makes your car sparkly (aluminum) is also keeping your front door from looking like a sad, faded banana peel.
