Display foreground and background in only 1 fill

[Anonymous]

Hello guys,
In AC, how can we have foreground and background pattern in only 1 fill? With this feature, we can create many many type of fill, vectorial hatch.
Example below:

Not possible I am afraid (without overlaying 2 fills).

The foreground is not the pattern, it is the colour of the lines in the pattern.
The background is the colour of the space between those lines.
The entire fill is what determines the pattern of those lines and you can only have one pattern per fill.


Barry.
