Umm, no, I think that would just confuse people even more, since now
you need to split a simple-to-understand continuous frequency spectrum
into lots of discrete partials.

In such a short article you can only cover so much.  If possible use
diagrams to show the time domain (e.g., square wave) and frequency
domain (dc-to-daylight) responses of R-C low pass and high pass
filters.The simple dc-to-daylight hand-waving is usually good enough
to get a feel for basic circuit behaviour, and then if readers want to
know more you can point them to online resources.  For example:
