Adjust onscreen text colors to make text visible on current background
In Atlantis, there are three color modes: Light, Dark, and Custom. You can switch between these modes manually through the dedicated section of the status bar, or the "View | Color Mode" commands of the main menu. When the "Automatically switch between the Light and Dark modes" option is checked:
Atlantis automatically activates either the Light or the Dark color mode depending on the current color mode of Windows. Note that this automatic option is available only under Windows 10 or higher.
To customize a color mode, select it in the "Color mode" box:
then change its individual colors displayed below in the dialog:
The "Main GUI color" is the color of the main components of the Atlantis GUI (toolbars, Control Board, status bar, etc).
To change the colors used to display documents in Atlantis, you can choose one of the color presets from the "Document color preset" box. Or you can change individual document colors. To do so, click an item from the "Document colors" box, then choose a new color from the box to the right:
System Color means that Atlantis uses its internal algorithms to determine the actual color.
Click the "Restore Default Colors" button to restore the default colors of the selected color mode.
When this option is off, Atlantis always displays document text onscreen using the original colors of the document text even when some document fragments are barely visible or completely invisible on their current background. For example, yellow text on a white background or black text on a dark blue background will be displayed as is (using these original colors) even though the text would be hardly visible and thus almost unreadable.
When this option is on, Atlantis may automatically change the onscreen colors of the document text to make the document text visible regardless of current document formatting, page background and other color settings. For example, an Internet address formatted with a dark blue font color will be barely visible under the Dark color mode if displayed with the original text color. When this option is on, Atlantis may choose a lighter or heavier shade of the original text color that will be better perceptible on the current background by a human eye. So, an Internet address that displays as dark blue under the Light color mode, may be displayed as light blue under the Dark mode. When this option is on, Atlantis may also adjust the color of the wavy underline displayed below potential misspellings.
If also the "Replace text colors with only black or white" option is checked, Atlantis may substitute document text colors with only black or white. For example, when this option is on, an Internet address that displays as dark blue under the Light color mode, will be displayed as white under the Dark mode, and text formatted with yellow font color on white background will be displayed as black.
Note that Atlantis never adjusts onscreen text colors under the Print Preview mode.
