A cuttlefish or squid can be used interchangeably, though they both share the same Chinese food name (鹵水墨魚). It is also shortened most of the time to just (墨魚).
The word "orange" has been used to distinguish it by color. The fruit orange does not have anything to do with the dish.
Cantonese cuisine
The orange color comes from food coloring dye. Some flavors are added in order to enhance the taste of the cuttlefish. It has a unique soft-crisp (Chinese: 爽; Cantonese Yale: sóng) texture, generally not found in any other meat.
