Color Gun

The Color Gun is a hand-held tool that allows the color theme of buildings to be changed, improving the aesthetics of the factory and allowing color-coding. It consumes one Color Cartridge for each use and has a magazine size of 100. When reloading, it consumes color cartridges from the engineer's inventory.

Unlock

 * It can be unlocked by completing the Flower Petals Research in the M.A.M..

Changing Color
While the Color Gun is equipped, to choose one of the 16 preset color themes. The preset color for each theme can be edited, but doing so will also update all buildings which use that theme. The top-left color theme is the default orange and blue that all buildings start with. Changing this theme changes all unpainted buildings.

Each color theme consists of two colors. In the right-click menu, the player can use the sliders to edit each color, which uses the HSV color space. By clicking on the numbers on the right side a number can be manually entered.

A building aimed by the color gun will be highlighted. The paint cursor at the center of the game window indicates whether the current target can be painted: if it is paintable, it shows the paint bucket icon with a drop. If not, it will show a 'X' beside the paint cursor.

Non-paintable objects

 * Electric Locomotive
 * Freight Car
 * Tractor

Current issues

 * When using a paint gun, it will cause the engineer's running speed to slow down for a brief moment, then resumes back to normal running speed.
 * When painting pumps, players must restart the game before the color change is visible.
 * When painting pipelines, the flow indicator will remain the same color as before while the rest of the pipe changes color. Players must restart the game before the color change on the flow indicator is visible.

Trivia

 * A color cartridge will be consumed even if the engineer aimed at nothing or painted a building with the same colors it already had.
 * Sometimes the color won't change instantly and will have a few seconds of delay.
 * Despite its description, it cannot paint vehicles, not even by changing the default color scheme. Train cargo containers will have the color of the current station for the load/unload animations until the animation finishes, after which their color reverts.
