Accent color

The project's accent color is fundamental. This color will be the highlight color for floors when hovering the exterior building image and the highlight colors for units when hovering floorplans. 

You can choose any HEX or RGB value.

You can make use of transparency by using the transparency slider as you see in the video below. A slightly transparent color is preferable over a completely opaque one, as it will show some details about the building and floorplan.
