Tactix Delta - cannot change accent color

I also can't change the accent color on that watch face, but I'm not sure I could even on earlier software.  Sorry, not very helpful.

Mine arrived with 6.0 software. The option to change the accent color was available, but nothing happened as I scrolled through that option on the watch face shown above. On the other Tactix watch face (analog watch) the accent option does change the second hand color.

Having the same issue after updating to v6.10

I recieved my Delta yesterday and updated it immediately to 6.10.  I can not change the accent color either.  On a side note, the mil spec face is my favorite, but I can't figure out what the triangle shaped barn is.  It's the triangle in the 7 o'clock position.  It migrates it's way around the circumference of the watch face.  Any ideas what it is?

That triangle points to the numbers on the outside of the bezel and shows the current UTC time 

Gotcha!  Thank you!

I have the Delta and like this face.  Never tried to change colors, but I like the black and white look.

But I just downloaded SHN TxD, which is like this stock face on steroids.  I paid a donation, got an immediate unlock code, and use my Open Weather API for lots of info. You can customize the colors on THAT face, as well as change the "Tactix" and "Mil Spec" to any other text, or battery %, date, even add a small center line under the time with several options, making it more useful with no more clutter.  Not affiliated, just a happy customer. I know a different face wasn't the question, but you can have what you're looking for with "SHN TxD" Here is an example of mine:

Got my Delta a couple days ago. It updated last night and I also have the same issue

A bit of a tangent here but any chance that watchface hits the F6?

I was able to change the accent colour on 6.10 and it’s working fine on 7.77b.
