Looking at your picture and the adverised picture, there isnt much in it.
Colour will never be 100% as viewed or expected because we all see colour slightly differently.
Also, we all use different devices & screens are all set differently, have varying colours, & are backlit.
However, given the number of happy customers, we consider we're close to good colour matching.
We use the same print file to advertise, as we use to print your order.
Your uploaded picture was taken in a dimly lit room, with dark surroundings and the wrap still on; our picture was taken in a naturally lit room with studio lighting.
