You will get the options as seen below.
Double click BackgroundColour to open the "Edit String" window.
Insert a color value in the Value data section.
Colors are noted in color format: RRGGBBAA, using hexadecimal notation. The Default value for the standard Cyan background color is: C3DFE0FF
NOTE: in MVN, AA (opacity) is not used, but makes the value data a standard format. You can use FF as input for opacity.
To get a chroma green color as background, you can use the value data:
Click OK and close the Registry editor.
You can now open MVN and see the new background color.
