One of Curiosity's cameras has a Bayer Filter Array and practically shoots like a DSLR. You can download the (debayered) "raw" files which are simply 1408x1200x1 (channel, uint8) panes one under the other in RGB order. So basically an 8bit grayscale 1408x3600 image that you can open with GIMP in "raw image data (.data)" mode and fill in the data in the settings window.

But you are right that many times scientific missions will have monochrome CCDs with a filter wheel on top (Cassini, Galileo, Rosetta, Dawn to name a few).
