Appearance Reiatsu Colors Different beings have different colors of Reiatsu, and it is not dependent on the individual's race or power. Certain combatants, like Ichigo Kurosaki, also have the color of their Reiatsu change over time or while using certain powers. The only time we've seen Reiatsu colored in the manga was Ichigo's Reiatsu; and it was gold instead of blue like in the anime.
So either everyone does have their own Reiatsu color, or everyone in the same species has the same Reiatsu color, or everyone's Reiatsu color is gold. Throughout the Manga/Anime, Ichigo's Reiatsu has had a couple of variations of colour, usually because of the source his power is coming from changes or alters. Like when in Bankai in the Soul Society Arc, his Reiatsu is Blue, until Hollow Zangetsu takes over when fighting Byakuya, from then.
As you can see above, Ichigo's Reiatsu in the manga is more of a golden yellow. In the anime, for whatever reason, they decided to change it to blue. It's one of those changes that leave you wondering why as it doesn't affect the story in any way, so why not just leave it as it was? It isn't as if blue is a more appealing color than gold.
Ichigo Kurosaki (黒崎 一護, Kurosaki Ichigo) is a human who is also a Substitute Shinigami. Ichigo is the son of Isshin and Masaki Kurosaki, and the older brother of Karin and Yuzu. He is also married to Orihime Inoue and has a son named Kazui Kurosaki.

Even in the manga, ichigo's reiryoku is portrayed as yellow. Just something I noticed. Old Man Zangetsu's Getsuga: light blue.
Shirosaki's Hollowfied Getsuga, FGT, Fullbring cloak: black. Now, what's the colour of Quincy techniques? Exactly. Shirosaki, the true form of Ichigo's zanpakuto.
Black, the true colour of Ichigo Kurosaki's reiatsu. It was. 15 What Color Is Ichigo's Reiatsu Supposed To Be? Battles Auras are all the rage in the most Shonen Battle Anime; whenever someone goes Super Saiyan in Dragon Ball Z, they get enveloped by a wave of golden energy.
Even One Piece has Haki - which is kind of a surprise, since that series is supposed to be about pirates looking for treasure.
