My first curries were the Australian 1960's housewife version of either curried sausages or occasionally lamb, but the curry sauce was the same. Garp, it was and still is surprisingly similar to chip shop curry sauce and I still love the curried sausages made that way. It isn't Indian by any stretch of the imagination but for me it is real comfort food. Onions, apple and sultanas but I've never seen pineapple used. I usually omit the sultanas as my wife isn't keen on them in the dish. Curried egg sandwiches was basically the only other use of curry powder in our home.
As for spiciness / heat / colour, my wife informs that when she was an exchange student to Sri Lanka her host family would prepare very mild curries for her assuming Western tolerance to heat. Her host father had his own special curries and they were invariably dark brown to black. The darker they were the hotter / spicier they were. Red curries weren't a thing.
