Color cameras produce color images. The most common color format is known as RGB. It uses 24 bits per pixels. Of these 24, each color (red, green, blue) is represented by an 8-bit grayscale with 8 bits corresponding to reds, 8 bits corresponding to greens, and 8 bits corresponding to blues. The result is more than 16 million diﬀerent colors.1
