Ik this might sound like a conspiracy but Sayori and Sephiroth literally complement each other, even if it is by coincidence
I mean, Sayori literally has the short coral pink (warm) hair which could reflect her warm personality and Sephiroth literally has the long silver white (close to cold) hair which could reflect his cold and bitter demeanor
Not to mention that Sayori is a short female and Sephiroth is a tall male
