couleur d’arrière-plan du visualiseur de carte

Question

Est-il possible de modifier la couleur d’arrière-plan dans le visualiseur de carte ?

Par défaut, elle est blanche.

Je ne parle pas du fond de carte, même s’il est possible de le faire en créant une zone d’une seule couleur couvrant une vaste région géographique (le monde entier…)

No, other than masking, there are not many more options. Masking might be a bit of a challenge to make it look seamless though (due to the jagged-ness of the coast line).

That is expected behavior...basemap will always draw first.  When I mentioned about a blue polygon, I meant one over the water only, with the coast as the one edge.  In ArcMap, this old-school workaround or masking is fairly straight forward (although othr ways to do that now too). With Online, this isn't as straight forward.

Maybe someone else has a better idea, know that what you are trying to do is a little more clear. Do you hve any more ideas MidnightYell2003  ?

Tried to put a big blue polygon under the cached base map and group them together as a multi-layer base map, but in the multi-layer base map, the polygon will always be drawn on top of the cached map, regardless the sequence they appear in the grouped base map. reference layer in the base map does not work either.
