The code color in Find the Dumplings looks to be tied to the numbered color clues shown in walkthroughs, especially the ones labeled yellow, blue, green, red, and purple. In one full guide, the code-related color clues appear at these spots: Yellow Number , Blue Number , Green Number , Red Number , and Purple Number.

What that means

The most likely answer is that the game’s code color is green for the main key/code clue you’re asking about, since a walkthrough shows GREEN KEY and GREEN NUMBER as the relevant progression markers. Another guide also points to code-related color hints in the game, but it doesn’t clearly state a single universal “code color” on its own.

Quick note

If you mean the exact color code for a specific lock, door, or secret , it may depend on the exact puzzle step you’re on in the game.
