AFAIK, that is Pentax's method of showing you which F-stop is the minimum recommended for a hyperfocal setting. Other manufacturers do that too (My Olympus XA has a similar color difference at f8).

I have recently acquired a few SMC primes and noticed that the f8 setting is colored in orange. Also, there is a similiar color of orange marked on one of the distance settings. Is this some kind of hyper-focal setting? Is this the marking for the best apperature, in Pentax's mind, for the given lens? Do the colored markings vary with different lenses, or are all the f8's this color?
Stupid question I know, just curious...
