For better visibility i use color fill legends of different color and different PATTERN. but i feel i would like the lines in the pattern to be wider. The Edit Color Scheme doesn't have an option to change line thickness:

The Pattern tool doesn't have an option:

if I use a pattern in a filled region, there seems to be a line weight option:

I did read there are ways to adjust line weight when used in a material, but none of those way seem to help with color fill legend.
How can I best adjust line weight of patterns used in color fill legends?
