As far as I understood the text, this is a system for improving the X-Y resolution of the finished picture, so that you with a 32x32 pixels array could create pictures of equal or better resolution than using a conventional array based imager, for example the 1024x2048 arrays used in the PanCam system of the rovers(they only use 1024x1024 for actual imaging though, the other half is used to buffer the image during frame transfer). The imager on the site you linked to is a variation on the scanning imagers used in some space probes, some probes used a single light sensitive element, a photomultiplier tube, so it imaged one pixel at a time, and used mirrors and stuff to rapidly scan the area. It is not so popular today, because it had higher mass and used more complex mechanics than arrays, though some probes do use a variation, single line arrays, and let the spacecrafts movement provide the other axis, this is likely why some probes create images that is of fixed width along one axis, but much longer along the other...
But this is not really the problem with color rendition in the final image, that would still have to be done in the same way as the system used today, with some sort of filters. Scientists would still want to use the full grayscale range of each channel, as that improves the detail you can get, so you would still need to post process each of the grayscales if you want something near true color. And you still have the problem of defining how to calibrate the imager system so that it gives true color.
And you'll need some way to calibrate your screen/printer, something like a densitometer, spectrophotometer or colorimeter, to ensure optimal color rendition. Still, it may not be true color, as the range of colors you can make with a RGB triplet is smaller than what the eye can see.
As the eyes are not stable in how they see colors either, true color can be a quite wide spectrum, it is hard to say...
