Look, it's Cinos and Sliat! No, I just got bored and I'm not counting these as OC's. The Sonic one I call Blur is based on me and 3 favorite colors while the Tails one I call Sparky is based on @SparkyLewis949 and I know she likes Purple and Red so I just also add orange 'cause it was the only other color I hadn't used. I don't own the original sprites, they belong to SEGA.
I use Sparky too much...
