Colors are difficult to portray 100% accurately for many reasons. One of the main reasons is everyone's device/screen is different with slightly different color settings which can lead to color variations.
The second most common reason is people will look at the flip flops at night and/or under fluorescent/artificial lighting which can have an effect on the color, and that's with any material. Our product photos are all taken in natural light to insure the true color is portrayed.
Therefore, we strongly advise you purchase a sample before making a large order.
