It wasn't easy to find, and the code is somewhat obfuscated.  

In src/interface_gui.c, down around line 9052, there's a block of code
that sets a char variable called "s" to some value depending on what sort of 
device an interface is.  (Aside:  single-letter variables make life so much
fun when trying to find where they're used...)  Down around line 9136, this 
variable is used in a call to "symbol" from src/draw_symbols.c.  This selects 
a symbol from the symbols.dat file from the "~" table (not a normal APRS 
symbol table) for the device.  In order to figure out what color corresponds 
to what device type, you have to read symbols/symbols.dat.  Which is really 
not easy.  That file describes, pixel by pixel, in ASCII characters, how to 
display an icon.  In order to decode the pixel colors, you have to look at
the function read_symbol_from_file in src/draw_symbols.c, to see what color
corresponds to what letter in the symbol.  

Most of the symbols for interfaces are just blocks of color in a particular 
shape, with the exception of DEVICE_SQL_DATABASE, which is a different shape 
and is not a solid block of color, but rather, speckles of different shades of 
blue, I think, maybe.

But if you work it through, it's like this:

  DEVICE_SERIAL_TNC:          #00008B  blue4
  DEVICE_SERIAL_TNC_HSP_GPS:  #00BFFF  Deep sky blue
  DEVICE_SERIAL_GPS:          #0000CD  mediumblue

  DEVICE_SERIAL_WX  or
  DEVICE_NET_WX:              #CD6500  darkorange2

  DEVICE_SQL_DATABASE:        (a mishmosh of blue speckling, can't tell)

  DEVICE_NET_DATABASE or DEVICE_NET_STREAM or 
  DEVICE_NET_AGWPE:           #FFFF00  yellow

  DEVICE_AX25_TNC or  DEVICE_SERIAL_KISS_TNC or
  DEVICE_SERIAL_MKISS_TNC:    #0000CD  mediumblue

  DEVICE_NET_GPSD:            #00CD00  green3
  DEVICE_SERIAL_TNC_AUX_GPS:  #EE0000  red2
