You can specify colours for text, clocks, tables, backgrounds and so on. The NTB has a basic colour collection so you may wish to add your own. You will need to know the Red, Green, Blue (RGB) or the Hex values for your colour before you start.
The NTB has a number of pre-loaded fonts but you may wish to add one of your own. You will need to obtain the font as a TTF or OTF file first and to rename ".OTF" files to ".TTF".
Note that font files in the "WINDOWS\Fonts" folder on a PC need to be copied using "Edit | Copy"
from the menu bar and pasted into another folder before they can be uploaded onto the NTB.
During its boot sequence and in between loading Layouts the NTB shows a yellow-green background. This background is also seen between the gaps in a Layout that is not covered with Zones. The screen background colour can be changed or it can be replaced by an image. The screen background image can be used as splash screen or serve as the background zone for layouts.
Setting the colour to black is not recommended as this makes fault finding more difficult.
