Despite this being a so called non-linear series (you can watch the episodes in any order and it still makes sense), I decided to watch them in chronological order and I'm glad I did.
If you would like to do the same, here is the episode order by timeline.
Violet - 24 years before the heist.
Green - 7 years before the heist.
Yellow - 6 weeks before the heist.
Orange - 3 weeks before the heist.
Blue - 5 days before the heist.
White - The heist.
Red - The morning after the heist.
Pink - 6 months after the heist.
The non-linear format : A nice idea but I would have been disappointed to end the series on certain episodes. Just my opinion though.
