My natural colour is grayish blue and they didn't change it too much. In fact, the only difference was really slightly larger iris. But that's not the problem. I need two different powers for each eye, and my lenses were from two different batches - I didn't even notice until I put them on and even then it took me a while to figure out what was wrong. One lens is fully printed (like in the picture), while the other has a slight gradient closer to the pupil (which looks more natural actually) and in daylight the difference is visible. I suppose if someone doesn't know I have contact lenses on, they might not notice, but it is there and from a short distance it does look 'wrong'.

However, the colour is pretty and accents my natural colour nicely.
