The DMK is strictly monochrome. Color is derived by series imaging with specialized color filters and calculated in final processing. This has many advantages; especially in terms of higher resolution and better processing. Of course, it's more complex and expensive.
The DBK cameras are 'bayer cameras'. This means they use a chip much like (maybe the same) that used on the toucams;
the pixels are overlaid with a mosaic of tiny Red, Green and Blue filters and some kind of magical math interpolation is used to derive the final color channels. The data is piped from camera to computer as an 8 bit file, and colorization is done either at time of capture and stored as 24 bit files, or by debayering the RAW file in processing later.
I assume the DFK series does the debayering in camera and sends the data in 24 bit format. This could make for some huge files and I'm not sure what advantage it would have over the bayer cam; but I could be wrong (I frequently am )
The tradeoff here is about a 1/3 loss (izzat right?) in resolution vs mono--the bayer system acts as a low pass filter and probably adds artifact in processing. Final results, however, are often limited by seeing conditions anyway. All in all, the mono RGB system is superior; but only if done correctly with each channel focused for its color (if necessary) and greater skill in processing.
