Graeme, could you help me to start this way? Where to look in the source? Or you may have a better idea?

That's certainly the simplest idea to hack something in.
Add a callout using system() to a script at the end of 
that passes the color value as arguments. Create a script that uses (say)
Image Magick to create a raster file, copy it to the photo frame,
sleep long enough to ensure that the image is displayed, and then return
to allow the instrument to do its reading.
