There was a specific reason why I named the American series :p
Though, thinking about it, Lost Galaxy and, ironically, Wild Force did do something similar with their 6ths, with the Magna Defender and the Lunar Wolf Ranger.

The colors of gold and silver are getting used way too much, way to often.

Magiranger/Mystic Force had a Gold.
Bakuranger/Operation Overdrive had a Silver.
Go-Onger/RPM had both a Silver and a Gold.
Shinkenger/Samurai had a Gold.
Gokaiger had a Silver who had a Gold mode.

In between that we've had what ... White twice (Gekiranger, Goseiger) and Violet.

Yeah it's time for something new than Green/Gold/Silver/White.

I like a mysterious introduction, like we saw with the Power Rangers adaption of OhRanger (Zeo) ... where we don't know who it is, but they're here and helping. A similar storyline from Abaranger/Dino Thunder where the White Ranger/Abarekiller was unknown for an amount of time.

Tired of the mentor being a Ranger.

Gekiranger did break the mold hard with GekiViolet :lol

Anyway, for mentors being rangers, while it is a little tired, it does make sense.

Also, what about Rangers sharing colors? Like TimeRed and TimeFire, or the Crimson and Navy rangers in Hurrikanger/Ninja Storm?

I don't mind 6th Rangers sharing colors ... but I don't now how it would work since Sentai has really pushed this idea that red=leader. Having two reds would really screw up that mentality now. And while that would be a GOOD thing, I just don't know how well they'd handle it, or how Saban would handle porting the storyline over.

Though I guess in Dino Thunder, Tommy/Black Ranger really was the "leader" and Connor/Red Ranger was more or less the "guy who runs in first and gets the power ups".

Wasn't Tommy essentially leader while he was the White Ranger and Rocky was Red Ranger too?

While 6th Rangers sharing colors has been rare, I didn't really like it.

If anything, I'd have called Gosei Knight a silver (or gold I guess - both colours are the most prominent other than black), which hammers the point home even more :lol

Gosei Knight wasn't actually a Ranger, though. He was like Sentinal in Operation Overdrive. They never morphed/henshin'd, or anything. So I don't think he counts... so leave him alone.

I don't really care too much, as long as they're not freaking silver again. Also it's about time we had an official orange ranger, just to complete the spectrum of colors.

No, just... just no. I can't imagine how horrible that'd look. Like a giant monster-fighting creamsicle.

Hey, you can't knock till you (or they, in this case) try it.

Oh! How about a Brown ranger too?
