我帮你们问了SCNK给艾伦上色绿眼的原因 @贴吧用户_5Re1D6K @拒绝完美 We believe that Eren's eyes are green because he is acting upon his own free will and his desire for freedom, which are things that we associate more with the Attack Titan than the Founding Titan. I suppose purple could also be a reasonable colour choice, but we felt that green made more sense.
