Both ends of the gamut

BOTH ENDS OF THE GAMUT

This is one that I am sure is said often, as it involves two expressions that describe distance – “both ends of the spectrum” and “runs the gamut”.   The color gamut or music gamut involves a range of hues or pitches, respectively.  When “both ends” is uttered, subconsciously one might be thinking gamut.    It really makes sense, and perhaps, like “shoot from the lip”,  should be acceptable.
