Main screen colours can be adjusted by selecting the relevant button (background, lines, text, ticks, graphs, hands1 and hands2) on the left hand side of the display and moving the 3 sliders. There are 2 colour schemes, one for night and one for day, which can be selected using the day/night button at the lower left. Pressing the default button resets the currently selected scheme.

Menu options allow to either display the day or night scheme or to automatically switch depending on the calculated sunset time. Your personal colour preferences can be loaded and saved using the file menu.
