This is completely wrong. ALL RGB files have three color channels, Red, Green, Blue, thus the RGB name. Some RGB files are compressed more or less, which affects color (JPEG). Some RGB channels are 8-bit (JPEG) or 12, 14, 16 bit (RAW). The bit depth affects the number of mixed (or added ) colors in the RGB file. For example, an RBG image (JPEG) can represent 256 x 256 x 256 levels, which is approximately 16.7 million individual colors, using a total of 24 bits per pixel (The Manual of Photography). A RAW file would have millions more tonal colors. All digital files are three colors and use the "additive" process for making other colors based on those three colors.

You certainly wouldn't want to make a print from a RAW file as it is simply raw, i.e. unprocessed. It contains all sorts
of junk that needs to be discarded, which is what is done for you to produce a JPEG version.
Often the "reason" for not choosing a JPEG is that the mfr. is making the decision for you. But JPEG is more than a processed picture,
it is a group of internationally known expert photographers who set the standard. If you know better, then you must be an expert.

The next common objection to JPEG then is that you will lose IQ (image quality) by improving your JPEG, but it can
actually take quite a lot before that happens. And to claim that it can not be saved from this is ridiculous because
you can make copies of the JPEG original and work on the copies, saving both the original and any # of versions without
ever degrading the original. The last "reason"for using RAW totally unprocessed exposure is that of being able to save a big
mistake such as over-exposure of white or highlights where visible detail is lost, and shooting RAW allows correction better.
However, that insurance against over-exposure is limited since if over-exposing has lost all detail it can not be recovered.
You will need more storage space if you save RAW files, and all that extra space is the junk you eliminated in processing.
You will need to convert to JPEG for most purposes anyway. 99% of the time I see RAW promoted on this forum, it is not
for doing something better but to correct mistakes, claiming everything can be saved with RAW and post processing, and
most of those "reasons" stem from not understanding one's camera, neither exposure nor the settings one can use
for the best image before pressing the shutter button.
Be prepared, however, that in asking the questions you chose, you stepped into a never-ending and very "uncivil" war of words,
opinions, and "reasoning". So look at the top of any page you are on and find the SEARCH option, press the button and find
that this subject has been argued to total exhaustion for anyone who has been here long.
