TFlxFillPattern.BgColor Field
Color for the background of the pattern. If the pattern is solid it has no effect, but it is used when pattern is automatic. Important: THIS COLOR IS IGNORED FOR SOLID PATTERNS, which are the most common case. If a pattern is solid you need to use FgColor. Please read the documentation in FgColor for a more complete explanation on why BgColor is ignored.
