Here are some Sonic sprites, inspired by sonic adventure 1 and shadow the hedgehog.
For the rgb values i suggest:
R:0
G:30
B:151
Viewing post in DIY Horse Race Thing comments
i suggest to change the name of the sprites to "SonicTheHedgehog", instead of only "Sonic", since it may enter in conflict with another sonic sprite made by https://itch.io/profile/spamtonkris wich i suggest you to download, so you can see a modern and classic sonic race togheter
