Copy color effect to other text

[PBog]

Hello,

I am not that experienced with GIMP and am facing following "problem":
On the internet, I found a picture with a name written on it in a kind of "calligraphy" style with a nice "ink look". (see picture attached)

   

I would like to copy the same effect ("calligraphy ink") on some text/name I have in my own design.
Off course, I chose a font representing the calligraphic look, but the color is always "flat". I would need/like to apply the "ink look" on to my font.

Does anyone have any idea how to achieve this?

I have played around with gathering the color pallete of the original and applying this as a gradient, but this didn't work out as I would like to. The effect still remained a "gradient" (logically) whereas I am looking for the "ink look".

Thanks a lot.
