At least the back of jersey is not dark. The black in the floral design keeps jersey colour from being too washed out from afar in bright sunlight. On a cloudy day, shouldn't be too worrisome.

Not every single jersey I have so far is in high vi colour, though 90% of them are. Some cycling I do is in quieter areas, just a hop skip and jump, several streets parallel to major arterial roads.

I worry particularily about high vi when I know the ride will extend into darkness hrs. or if I'm going on a long ride where another rider(s) need to see where I am at... But by default, most of my jerseys are high vi anyway.

It looks like a great jersey to also wear when stopping by to visit/chat up for a few hrs. with friends. If you look good in the cut, colours, go for it.
