YOU SAID:
Let's sway while colour lights up your face
INTO JAPANESE
色が顔を照らしながら揺れましょう
BACK INTO ENGLISH
Let the color shake while illuminating your face
INTO JAPANESE
顔を照らしながら色を振る
BACK INTO ENGLISH
Shake your face while shining
INTO JAPANESE
輝きながら顔を振る
BACK INTO ENGLISH
Shake your face while shining
That didn't even make that much sense in English.
