Hi everyone, my first post and also my first question 
I have Question about the colour picking process during a polypainting.
Is there a posibility to put the colour picker on a keyboardkey? Because it is realy time consuming if i have always switch to the colour palete everytime if i want to pick a colour from my model.
Not directly. But you could record a macro of you selecting a specific color (or setting its numerical value in the Color palette). Once the macro is created, you can add a hotkey to the macro, allowing you to invoke it with a keypress.
hm ok, but this is only for a specific colour?
The hotkey āCā will pick the color under the cursor.
See here for other hotkeys:
