My interpretation is that the original colorway should always be refered to buy it’s color details on the box.
The nickname tiger was not around in 98/99 era, when my friends had them we never called them that at least. I believe the nickname tiger was born in the second wave of releases in 2002/2004 in the US and Australia maybe even France too, but again it was to the best of my knowledge not a name given to them by Nike. Important to note the color change after the 98/99 release and it never went back to the original vibrant orange it was first introduced as. It moved to a fuller shade and over the years most recently in 2013, It looked more like a tiger orange than a sunset orange. I remain hopeful that this weeks relase is closer to the original.
What we have seen in recent years is the name Tiger stick so much so that retailers even list in on their websites as tiger, I have seen footlocker Europe even confused, in the last few weeks it has come up and off the release calendar as a tiger and a sunset.
Logic says that the orange is based on a sunset as is the hyper blue, as we have all seen the inspiration picture. As to whether it is a sunrise or sunset, billy made a nice comment a few weeks back about the shoes maybe representing different times of the day, different colours of the sky representing the different time periods, that’s another way of looking at it. We would have to ask the designer to be sure about the inspiration for the orange pair.
For me the original looks like this, a sunset. See the color reflecting on the water, that’s what the originals look like.
