Hmmm, that isn't the most accurate or scientific of approaches to be frank.
They are merging a bunch of different physical/chemical processes into one system intended to do 'everything' in one go instead of using a stepwise approach of performing each part of the whole - i.e. each separate change having it's own process, stop by step.
For example a part of the process is one of physical filtration, and another is one of adsorption (the use of activated charcoal) which is a different process to filtration, etc.
This appears to me (admittedly from a cursory inspection) to be more a process of convenience rather than one of efficiency and quality. When the various processes being used to concentrate and purify the terpenoids are separated out as individual stages, each can have it's own ideal conditions for a maximum result (whatever your chosen criteria) such as having an ideal temperature to run at, there's no clash of conditions whereby everything is a compromise and lowers the quality of the result and/or loses more as the process is less efficient.
Regards the colouration, this can be very deceptive as an indicator of 'purity'. Quite often the nature of some of the degradation products of the terpenoids and related compounds can be like dyes, and the tiniest amount can make a marked colouration. In other words, removing that discolouration may involving losing maybe 0.00001% (very rough ball-park figure) or less of the total mass of the concentrate.
This is where the activated charcoal will do it's thang, with the relatively tiny amount of the dye adsorping to the surface of the fine granules of charcoal so after filtering it leaves a fairly clear solution which evaporates to leave a straw coloured (or similar) shatter/wax/crumble/what-have-you.
But no amount of filtering alone is going to manage this effectively.
Colouration also comes from the elements initially extracted from the plant, not all of which are active, and in addition, as described above, the various degradation products a complex mixture of volatile and unstable alkaloids are an added part to the picture.
But the bottom line of what I'm failing to describe very well, is the cruder the process, the less efficient it will be, with the balance of quality and quantity being defined by the process(es) used, but overall diminished in the output.
For the very best control over what you end up with, doing it in stages in the most efficient order will give the best quality and quantity while allowing the most control over the nature of the concentrate being produced.
I don't like the appearance of pseudo-science in that linked page and the inaccurate descriptions used are either unjustifiably patronising or deliberately misleading (in my view at least). I'm not saying CRC definitely doesn't have a place under specific circumstance (where higher losses or less pure product are acceptable) but the misrepresentation makes me suspicious enough to question it carefully before using it, should I be looking for a method.
