Painting by the Numbers

摘要

Have you ever gone to a paint store to match a color sample? Were you amazed when they produced an exact match of your sample's hue, color and saturation? You went home, spread it on the walls right next to the original, and no one could tell the difference. A paint store miracle? Not really. The paint-mixing machines have built-in colorimeters to measure the sample, and they have built-in devices for depositing the required pigment combinations to match it. The driving software engine contains a mixture model that instructs server motors to deposit the right amount of pigments to blend with the white base paint to create a paint that matches your sample closer than your eye's ability to detect the difference.
