Very Light Grey
From PixelPlace Wiki
Very Light Grey is the color of the Border in the PIXELS WORLD WAR map and others like canvas 8,9 and 10. This color makes up oceans and lakes, as well as divides countries as the borders.
The color is also the space beyond the canvases, which you cannot interact with.
It is the only color on the map that is not in the Color Palette. If you try to use Alt + Click to choose that color, you won't get the color.
