Program Colors
In the 'Program Colors' options-page, you can choose to configure a number of other program colors that refer to the program Graphical User-Interface rather than the colors used for the maps.
The 'Theme Colors' refer to colors that are used to color all standard items within the program windows: buttons, labels, selectors, etc.
The 'GridView' colors refer to the colors used for the sortable data-tables on the 'Vector Map', 'Tables', 'Main Log', and 'Auxiliary Log' tab-pages.
To change a color, simply click on its colored square. A 'Color Picker' window will open. You can choose any of the basic colors shown on the left, or create your own color on the right by dragging the Hue cross around the colored window, moving the Luminosity Slider up or down, or typing in HSL or RGB values in the range 0-255.
