If you put negative values for aspect and amplitude, you can get the mirrored coil, add this in the @marmot's answer may complete the desired output; also I added an option using markings to get some similar drawing that uses scope and yscale to invert the marking, then a new variable to control the coil color,when the path is straight it has good result, markings path lacks bending good results.
EDIT: Added a control for marking step to improve bending results.

Acording to @marmot's suggestion closing the gaps and drawing all the variations, using \pgfdecoratedpathlength, /pgf/decoration/mark info/sequence number.
