Dear Son,
add "/color" to the device call (immediately after your set_plot,'ps' command).
Cheers,

PS mom sends her love. :)
From the help:
The DEVICE procedure provides device-dependent control over the current graphics device (as set by the SET_PLOT routine). The IDL
graphics procedures and functions are device-independent. That is, IDL presents the user with a consistent interface to all devices.
However, most devices have extra abilities that are not directly available through this interface. DEVICE is used to access and
control such abilities. It is used by specifying various keywords that differ from device to device.
See IDL Graphics Devices for a description of the keywords available for each graphics device.
Syntax
Note
------------------------------------------------------------ --------------
Each keyword to DEVICE is followed by the device(s) to which it applies.
[, /COLOR{PCL, PS}]
