[KevO]

Scanning down towards Brest and sections of the chart on Navionics have changed colour? Whaassuup?

Is that Navionics chart on a plotter? May have something to do with the settings, I had something similar in that area some years ago. I do not remember the precise solution, unfortunately.
In my Boating app everything looks normal.

Is t just the french chart colours?
If you mean the red dots its something to do with your low water settings.

It’s in the boating app. Some bits appear ‘normal’, others have changed significantly it seems. Only noticed it for the first time last week. All seemed normal the last time I looked.

It's most likely a superimposed display of the SHOM "Nature of sea bottom" layer, complete with the usual Navionics imaginative interpretations

It’s called “seabed areas” in Navionics boating app in the layers settings.
