background() return color?

I just upgraded from v58 to v66 and noted that background() no longer returns a value.
i suppose it makes less sense for background() to return a value, since it is no longer persistent.
on the other hand it would be useful for calculations if background() would return its last value(at least for me.)
thanks - jw

yeah, we removed those, since they were weird api, and we couldn't quite imagine why people wouldn't know what background/fill/stroke color they had used.. i'd be curious as to how you were using it.
for now, you can use
color b = g.background;
which will give you the background color, though if it's an image, that'll just return the last color used.
these should also work:
color s = g.stroke;
color f = g.fill;

thanks for the above, that will work just fine.
in an app i created the background color changed dynamically. so a routine was used to determine foreground colors of proper hue and contrast.
i preferred referencing the return value of background() rather than storing it in a separate variable.
