Super Sonic is gold.
Burning Blaze is pink.
Blaze is Nega Sonic.
Super Sonic [gold] is an inversion of Sonic being blue.
Blue <-> Orange (Yellow?)
Sonic <-> Tails
Tails contrasts Sonic, similar to Blaze in many ways, such as being bullied and insecure deep down. But where Blaze combines that with Knuckles' anti-Sonic traits to further separate herself from Sonic, Tails follows in Sonic's footsteps in direct imitation of him to bridge the gap between them.
The one who contrasts Blaze the most is Amy. There is a similar trait of intense, passionate emotion, but everything about Amy is a girl version of Sonic. She does what Sonic does, she likes what Sonic likes, she's as much of an inspiration as he is at times, but she does it with passion and enthusiasm. Blaze's whole thing is concealing those intense emotions with strict discipline, the direct antithesis to Amy being so wild and carefree by comparison. Compare Amy to how Cream & Marine are used as Blaze's equivalents to Tails, and there is a common ground here. Especially Marine, who actually contrasts Blaze as well. Where Blaze is closed off, this younger girl is much more open and enthusiastic.
Therefore, if Blaze is the Nega Sonic, then the Girl Sonic (Amy) is the Nega Tails.
Tails is a similar color to Super Sonic, Amy is a similar color to Burning Blaze.
True "Sonic" stories are never about Sonic himself, but about the development of someone else with Sonic as the vehicle/catalyst for that growth. Tails & Amy are the ones who primarily follow Sonic at all times, with growth and development being a backbone for both of their stories in the past.
Therefore, the core of Sonic stories should center primarily around Tails & Amy as the reflection of the impact Sonic has on the world. From the eyes of the Kid-Sonic who wants to be just like him, and the Girl-Sonic who is head-over-heels in love with him.
