Wow, so this is an old thread now… but after using darktable for some time and having just recently read darktable 3.0 for dummies: hardcore edition, I was inspired by @anon41087856’s handling of LEDs and decided to revisit this photo using darktable 3.0.

I didn’t attempt to match colors to Fujifilm’s JPEG rendering, but I did warm up the midtones after first correcting color a bit (based on a building I thought might be approximately “neutral”).
I did also mask the bridge in the color balance module I used for the warming effect, as I also boosted saturation in the same module. I thought the bridge already has a lot of character in the photo, so it didn’t need any more help. 
In addition, I did push local contrast up a bit more than usual, but it’s a city scene and darktable could handle it (and can handle even more than what I went with), thanks to sticking with the modules @anon41087856 worked on and suggests.
