Lamp Colour Changer

Paint lamps and lamp ghosts with solid colours or gradients. Choose your settings, click Select lamps, and drag over an area.

• Colour picker with RGB sliders, hex input, a live lamp preview, and an eyedropper.
• Gradients with separate start and end colours. Blend horizontally, vertically, diagonally, or outward from the centre of the lamps being painted.
• Favourites for solid colours and gradients. Rename, reorder, or delete them. Gradient presets show both colours and remember the direction.
• Independent colour and always-on controls with an option to skip circuit-controlled lamps.
• Undo and redo for up to 20 selections.
• Selection summary showing how many lamps and ghosts were updated and how many circuit-controlled lamps were skipped.

Open the picker from the shortcut bar or press Ctrl+Shift+L. Use Ctrl+Alt+Z to undo and Ctrl+Alt+Y to redo. You can change these shortcuts in Factorio’s control settings.

Requires Factorio 2.1. Space Age is optional.
