The dark color is a background whereby the charming drawing is in a bright color. The mixture of these two colors makes an object looks sharp and people normally get attract and staring at it.
With a splash of drawing on polyester fabric that used to prevent spray of bathwater from getting out from the bathtub, it is an instant way to refresh your boring bathroom to luxurious appearance.
Better still, you can choose based on a drawing that perfectly fits your bathroom theme. For example, the first one featuring a golden tree is the smart choice for the modern bathroom.
I personally love the third one with blurred lights which gave me a phantasy feel. Alternative, you may consider the last options if you prefer the vintage style.
