Describe the Bug

When changing the polygon fill color to for example white (#fffff) it doesn't affect the label. The result is still the same (polygon filled with red scarlet). Tried to change it via the generated JSON file but still doesn't affect the label image.

Expected Behavior

the label image should contain the polygon filled with white color and the background as expected black
