Comparing the surface printed stamp with the photogravure stamps is plain silly. Those colours will not look the same even if they are.
As GeoffHa wrote, check the watermark first. There are three watermarks, only one is a contender. Then, consider the description is "very yellow ("Cyprus") green. Yours lacks the yellow tinge. It is almost impossible to identify the shade from a scan. However, I would put my money on a bright green shade.
With the usual caveats regarding pictures on the web and shades, here is one Spink prepared earlier.
