Sunset is kind of an odd colour when I look back at some of the pics of my Zed over the last 5 + years. In the shade in some pics looks really quite dark, but then you get stunning reflections. Then in full sunlight, the paint literally glows. It does tend to draw a lot of attention just sheerly because it's so bright, this can be a bit of a negative.
Pluses, easy to find in a line of cars, or in a carpark. Colour hides road muck fairly well from a distance (if you've been on a long drive), not as well as a silver one obviously. Good colour for a convoy leader.
Minus, being so bright, is a bit distinctive so can receive a bit of unwanted attention.
Ultimately the colour is a chameleon.
Doesn't matter what colour you go with, it's still a Zed.
