I think not

you can open the picture in paint, then select the color with the picker, then edit the color and note the RGB numbers for to use them in GG.

If you want to know exactly the RGB or Hex code of the colour of an object in GeoGebra, right click on it, then select Properties (Settings in v.6), and the Colour tab. You will see the RGB or Hex code of the object's colour displayed on the bottom of the colour palette.

By pressing the + icon you can create the color you want for an object, entering the desired RGB values.

Sorry for the Italian interface :)

I hope it's clear that it's the Color tab of the Properties dialog of the object.

I repeat me

you can open *.ggb file with zip, then extract the picture, open with paint ..........................etc

you can also download a general tool colour picker like
