Field Attribute Color is used to set the Field Contents in the specified Colour only in Display Mode. If the same needs to be printed in the specified colour, the Colour must be set using Field Attribute Print FG.
Example
[Field: Fld Color]
Use : Name Field
Set as : $Name
Color : Red ;; This renders the colour in Display Mode
Print FG: Blue ;; This renders the colour in Print Mode
Tip: If the Background Colour needs to be set during Printing, the same can be done using Field Attribute Print BG and Field Attribute Background sets the Background Colour in Display mode.
