Multicolor Edges Coloring Style/Schemata

Is there a way to change the coloring Style/Schemata for multicolored Edges?

I want to ask if it is possible to draw something on the line of the brown/white one at the top:


or the Green/White, White/Black/Orange and Blue/Black/Yellow ones here:

These were done by stacking Solid, Dashed and Doted line on top of each other, but this sometimes leads to problems.

The Edges normally have a Black other Line #000000:<inner colors>:#000000 and the other colors inside.

Here is a link to a possible solution for SVG output.
