Garmin Echomap Charts

[Mikeyman104]

Anyone know how to change the color setting on the chart views for a Garmin Echomap 73sv? I'm used to charts showing a darker shade of blue for shallower water and then a lighter shade or white for deeper water, similar to the Navionics chart viewer. However, the charts on my new unit are showing the opposite. Darker blue for deeper and lighter for shallower and it's kinda driving me nuts. I've seen the shallow shading rules in the settings, but this appears to be something different. Probably something stupid that I've missed but just wondering if anyone had any thoughts or experience with this.

Spoiler: my dumbass had it in night mode so it was all backwards 😅
