Is the meat curry powder mentioned for use in Malaysian curry puffs similar to western chili powder
Store brands of curry powder sold here in the UK (and I assume most western countries) don't usually contain chilli powder at all. Chilli is generally added separately to taste, because many westerners can't handle the heat of a hot curry mix. The typical yellow colour of these mixes is because they contain turmeric.

However it looks like the Malaysian curry mix in the photo does contain chilli.  After looking at the bright red colour, perhaps it contains Kasmiri chilli powder which is very red, but quite mild, or perhaps it even has red food colouring in it.

Chilli powder alone doesn't make a curry, it needs the other spices commonly found in curry mixes such as, corriander, cumin, clove, cinnamon, black pepper, fenugreek, etc, etc.

When I want to make my curry extra red, I use Kashmiri chilli powder together with either regular curry powder or garam masala. It not only has a wonderful vivid red colour, but it's fairly mild and yet still flavourful, so I can afford to put more in the curry without making it totally inedible.

I have had a couple of Malaysian curry mixes given to me by a friend, and when I checked the ingredients I did notice food colouring was an ingredient, also their curries also have a distinctive star anise/fennel seed taste, so it might be worthwhile adding these spices too, if they aren't in your store bought curry mix.
