Super Sentai Color Patterns

I just covered similarities and differences in color and team member numbers through the decades, but I want to cover this unspoken rules of colors for teams and team numbers. These do vary.

Teams start with 3, 5 years apart, unconventional colors

2002 - Hurricanger: Red, Blue, Yellow, Crimson, Navy, Green; Started with 3 and unconventional colors are Crimson and Navy.

2007 - Gekiranger: Red, Blue, Yellow, Violet, White; Started with 3 and unconventional colors are Violet and White as an additional ranger. 2002 and 2007 are 5 years apart obviously.

2012 - Go-Busters: Red, Blue, Yellow, Gold, Silver; Started with 3 and unconventional colors are Gold and Silver as fourth and fifth instead of sixth and seventh. 2007 and 2012 are 5 years apart obviously.

 Teams start with 5 and conventional colors after unconventional ones in groups of three

1998 - Gingaman: Red, Blue, Yellow, Green and Pink
1999 - GoGoV: Red, Blue, Yellow, Green and Pink
2000 - Timeranger: Red, Blue, Yellow, Green and Pink
These three had these same colors, four years later there was Dekaranger. But granted, they didn't come after an unconventional one.
2004 - Dekaranger: Red, Blue, Yellow, Green and Pink

 2005 - Magiranger: Red, Blue, Yellow, Green and Pink

2006- Boukenger: Red, Blue, Yellow, Black, and Pink
These three came after the unconventional Abaranger and Hurricanger, they started with 5 and had conventional colors.

2009 - Shinkenger: Red, Blue, Yellow, Green and Pink
2010 - Goseiger: Red, Blue, Yellow, Black, and Pink
2011 - Gokaiger:  Red, Blue, Yellow, Green and Pink

Goseiger is 4 years apart from Boukenger to have the same color scheme, in fact both had Silver Rangers. Shinkenger, Goseiger and Gokaiger all came in a row and had conventional colors and came in after Go-Onger that started with 3 and didn't have a Pink Ranger.
2014 - Tokkyuger: Red, Blue, Yellow, Green and Pink
It is expected the next seasons will start with 5 members and have either green or black with pink and yellow rangers.

Slightly unconventional colors after completely unconventional season, 5 years apart
2003 - Abaranger: Red, Blue, Yellow, Black, White; Not completely unconventional, in fact same colors as Gaoranger but Abaranger started with 3 and ended with 5. It came after Hurricanger.
2008 - Go-Onger: Red, Blue, Yellow, Black, Green; Not completely unconventional but the last team to have this color scheme was Liveman in 1988, about 20 years apart. It then had not only one metallic color but two: Gold and Silver. It came after Gekiranger.
2013 - Kyoryuger: Red, Blue, Pink, Black, Green; Not completely unconventional but it had no Yellow Ranger, the first to do so since Changeman. It came after Go-Busters.
