What? There's never been a color code that used green for 16. Never been
a color code that used a single color for two digits. Never been a
consistent capacitor color code.
I'd say your red green red capacitor is 2500 pf. Red for 2, green for 5,
red for x 100. Never the multiplier first. With only three colors no
designation for voltage.
There certainly is such a thing as a 116 uf capacitor, but not used for
RF and not marked as such. It would be marked and sold as 100 uf.
Diode polarity is only critical that it match meter polarity. Either is
useable.
There's a frequency selective FSM design in older ARRL handbooks and I
think maybe G3VA's Amateur Radio Techniques book. Generally what you
need is an antenna, a tuned circuit, a diode and a meter. Sometimes you
need a little DC gain.
