So you know how Sasuke's rinnegan has the sharingan toma things on it whereas standard rinnegan doesn't, could this mean it is a different version of the eye?
and what did you want to him to make exactly? its the same as sages moms third eye and it will tie into story and plot dont worry bro he did it for a reason
Red does look better. Since both his eyes are different, the least it should be is having the same color. Besides, red fits his eyes better than purple.
