It depended on the colour of the car and again, someimes the interio trim combination.
Healey Blue cars usually had very dark blue (almost black at a glance) main dash panel with a dull silver instrument pod, whether single panel or the early 2 piece. Some early 2 pc. dash Healey Blue cars had a Healey Blue instrument pod, but this was more an exception than the rule.
White cars with orangey red interior usually had white dash with dull silver instrument pod.
Spruce Green cars with dark green interiors generally had Spruce Green dash with dull silver instrument pod.
Red cars usually had completely black dash but some had dull silver instrument pod, this usually with black intriors, but a red car with a red interior could have a red dash, usually with dull silver instrument pod.
Black cars with oragey red trim had black dash with dull silver instrument pod.
There were exceptions to the above but this was generally the practice.
The leather covered dash was technically a Warwiick option but only one original car has ever been documented, so I personally would never go there unless I had factory documentation of that particular car having it. Covering the dash and cockpit rails would of course be your personal choice, but it looks to me to be just an easy way to cover up damaged cockpit rails and poorly painted dashes.
