Am I tripping right now?

I used the process of elimination:

It cannot be that she is a witch because everyone knows that witches have black hair. Plus if she's a witch, why turn the color of her hair from violet to blue? Why not set her hair ablaze as she walks into the other room? That would have made the video go even more viral.

It cannot be that she is a unicorn because she is not a single corn. Someone is clearly filming her hence she cannot be single. Her house seems to be neat and it doesn't have COBwebs. Hence she doesn't have cobs and she cannot be a corn.

It cannot be that the dress is white and gold because her dress is definitely grey with "playlist" printed on it in white. Besides, the answer to the question "what color is the dress?" is (A) All of the above (nigahiga reference).

It's always safe to blame things on what we perceive and leave things unanswered by asking "What is reality?" Hence the answer.

Also left out the part where the nature of light source (Is it led, incandescent, fluorescent, sun, or shade) directly impacts what portions of a spectrum are reflected, and thus what color we perceive

She is cute She is cute She is cute She is cute She is cute She is cute She is cute She is cute She is cute She is cute She is cute She is cute She is cute She is cute She is cute She is cute She is cute She is cute She is cute She is cute She is cute She is cute She is cute She is cute She is cute She is cute She is cute She is cute She is cute She is cute She is cute She is cute She is cute She is cute

she is a unicorn of course why is my answer wrong

Light source and shade contrast. Keep it simple. Hair does not change color at all. Perception is the culprit.

She is nymphadora tonks

it's dipend on wavlenth of light in each rooms because by wavlenth of light are effect on a colour of hair

See all option ,when the light reaches at a thing and reflect to our eyes then we can see the object so hairs will se only when light falls on it (on that part)

Answer will not ever than B Simple
