Just out of curiosity I tried the following:
draw dashpattern(on 2 off 6) scaled 5pt withcolor blue;
draw dashpattern(off 4 on 2 off 2) scaled 5pt withcolor red;
dp := currentpicture;
draw origin--(5cm,0) dashed dp;
But of course "! Picture is too complicated to use as a dash pattern."
So you have to draw the path twice with different color and pattern
(you can write a macro for it of course if you need it often).
pickup pencircle scaled 2pt;
dp := dashpattern(on 2 off 6) scaled 3pt;
dp := dashpattern(off 4 on 2 off 2) scaled 3pt;
path p; p := (origin .. (2,1) .. (3,-1) .. (5,0)) scaled 3cm;
draw p dashed dp withcolor blue;
draw p dashed dp withcolor red;
