I created a web app where the default basemap is ESRI's topographic map, which is mostly light colored, so I draw the main layer using a darker color. When I switch the basemap to imagery, it doesn't show up as well. I'd rather not switch to a color that shows up well on both just because the original color I picked matches so well with the theme of the map. So is there a way to configure the app so that when you switch basemaps, the symbology of the layer in question would automatically change to a color that is easy to see on imagery?
