And if anyone is using LiveCode or OpenXTalk IDE to mess around with Decker here's script for converting an image control contents to another image control with the required Mac II color palette:

on mouseUp
    export image "Original" to myVariable as gif with palette getDeckerMacIIPalette()
    --  set the text of another image control to myVariable to preview:
    set the text of image "16ColorVersion" to myVariable
    --  then you can save the new gif to a file with:
    --  where tFileName is a file path you provide must provide --
    --  open file tFileName for binary write;write myVariable to file tFileName;close file tFileName
end mouseUp
function getDeckerMacIIPalette
    get "255,255,255" & cr & \
   "255,255,0" & cr & \
   "255,101,0" & cr & \
   "220,0,0" & cr & \
   "255,0,151" & cr & \
   "54,0,151" & cr & \
   "0,0,202" & cr & \
   "0,151,255" & cr & \
   "0,168,0" & cr & \
   "0,101,0" & cr & \
   "101,54,0" & cr & \
   "151,101,54" & cr & \
   "185,185,185" & cr & \
   "134,134,134" & cr & \
   "69,69,69" & cr & \
   "0,0,0"
    -- the sorting of this list effects the resulting image
    sort it numeric by item 1 of each 
    return it
end getDeckerMacIIPalette
