Sorry to say the blue-tailed Tonys are bogus. The tails on some Tonys were red and this meant they were part of an aerial ramming flight (Shinten Seikutai).
For a completely up-to-date survey of Ki-61 and Ki-100 markings, watch out for Osprey's upcoming title on Ki-61 and Ki-100 Aces. It corrects many mistakes currently prevalent in Ki-61 profiles, scale models and artwork.
https://ospreypublishing.com/ki-61-and-ki-100-aces-pbAs a generic pointer I can say the following:
* Tonys with blue tails didn't exist;
* Anti-glare panels well blue-black, which in practice was black or very dark grey (depending on age), with a blueish tone. They were not blue;
* Blue was indeed used for the HQ flights, but this manifested itself mostly in blue stripes and wheel door numbers - never blue tails;
* Spinners were usually painted glossy dark brown. Coloured spinners did exist, but typically only the front part was painted;
* There were no known operational Tonys with red leading edges (unlike what's suggested by some recent sources);
* Droptanks were typically olive brown (officially: "yellow green nr.7") from 1943 onwards and usually blue-grey before that time. Only one well-decorated 244th Sentai Tony was reported to have yellow droptanks, but this was an exception, definitely not the rule.
