Visual ambiguity caused by sameness of color

Using color to visually identify the property type is an excellent idea. But they way it has been implemented here is not at all useful. The reason is that the identifying colors are: seven types all share a similar shade of aquamarine (bright blue-green) and two types are white. There is not enough variety to clearly differentiate amongst them. If the intention was to limit the range of colors for aesthetic reason, this can still be done while still using blue, but using adjusting the saturation and lightness while keep the hue the same (see HSL color model). I express no opinion as to what color scheme should be used, but the current colors do not accomplish what is intended, and therefore must be changed.
