Question: how to change the background color of a bifurcation figure

with(IterativeMaps);
with(ImageTools);
Logistic := Bifurcation([x], [r*x*(1-x)], [.5], 2.5, 4);
ArrayTools:-Dimensions(Logistic);
ColouringProcedures:-HueToRGB(Logistic);
Embed(Logistic);

This is the code for Bifurcation program of the Logistic map. How can I change the black background color of this figure, and How can I save this figure.
