Should say fill type: colour, and then have a little box under it. Double click and change your colour. Make sure you have the "stroke" menu highlighted (not just the box checked) that gets me all the time.
If you click on 'Stroke' (On the left) in the blending options window, then you get the options for the stroke; underneath the 'Structure' section is an option for the 'Fill Type', so click on the Color (Colour, surely? Damn Yanks!) box & it should open up your Colour (hah) Picker.
