By using elements that are sensitized to red, green and blue light.
Film has three emulsion layers stacked one atop the other. The layer sensitive to red light forms cyan dye when you develop the film, the one sensitive to agree produces magenta dye, and the blue-sensitive layer produces yellow dye. The more dye is formed, the less of that color of light will go through the layer.
Digital cameras put a Bayer filter, which is a grid of red, green and blue filters, over the sensor. The computer in your camera knows what color of light each pixel is supposed to receive and assigns it to the proper channel.
