Colour dreams are rarer than people assume, and yellow specifically tends to be noticed rather than atmospheric..
What research shows
Around 80% of people dream in colour, but only a minority report colour as a salient feature. Studies of people who grew up with black-and-white television found higher rates of greyscale dreaming, which is the clearest evidence that dream colour is learned.
The psychological reading
When a colour is the memorable element, it usually attaches to a single object rather than the whole scene.

The version matters
Most dream dictionaries give one meaning for the whole symbol. In practice the specific version carries most of the information — losing every tooth and losing one tooth are not the same dream.
How to record a dream, why the feeling matters more than the content, and when recurring nightmares are worth a doctor rather than a dictionary — set out once on the main page.
How the dream felt matters more than what was in it. The same image can arrive as comfort or as threat, and that difference tells you more than any entry in a dictionary — including this one.
