They often strongly feature the colors red and blue, along with black, white, green and golden yellow.These are primary and bold colors, accenting Ash's primary status in the series.
One of the curious notes about Ash's first outfit is that unlike May, Dawn, Iris, Cilan, Serena, Bonnie, Clemont, Lana, Lillie, Mallow, Kiawe and Sophocles while it is clear his clothing is directly inspired by Red's, it is a unique outfit design in its own right.
This fact is also echoed by the outfits of Brock and Misty, which were designed purely for the anime instead of using the outfits seen in the games themselves and the artwork for the games.
The upper outfit is a medium blue jacket with gold trim and white collar and sleeves, worn open over a dark cyan or teal t-shirt.
Ash kept his Kanto, Orange League, and Johto Badges pinned to the inside of the jacket, which from time to time, would be taken off by him, most notably when his Pokémon need warmth.
This is a list of the different clothing and outfits worn by the main characters.
