Planet Class and Usable Tiles
A planet's class determines the number of usable tiles on its surface. Green outlined tiles allow for the construction of any available improvement, while other colored tiles require specific technology to be converted to general use.
The majority of the colony screen is taken up by the map of the planet's surface. This map is overlaid with a hexagonal tile grid. Each tile represents an area where an improvement can be built. Gain access to more improvements or more tiles on the planet's surface through research projects in the tech tree.
Planet Features and Tile Bonuses
Some tiles have special features that give bonuses to improvements built on them. These are denoted in-game by a small colored graphic icon at the bottom of that tile. Mousing over the icons found in these tiles will provide a brief description of the type of feature present and give a suggestion as to what types of improvements would benefit the most by being built there. In general, the colors of the icons will also provide at-a-glance information as to the benefit bestowed (orange boosts manufacturing, gold boosts income, dark blue boosts research, etc.).
