The phrase "feeling yellow" is not a common idiom or expression in English. Therefore, it's difficult to provide a definitive meaning without additional context. In some cases, people might use colors metaphorically to describe their emotions or states of mind, but the interpretation of "yellow" in this context would largely depend on the individual's personal associations or cultural references.
For example, in some cultures, the color yellow might symbolize happiness, joy, or warmth, so saying "feeling yellow" could imply that the person is in a positive or cheerful mood. On the other hand, in some contexts, "yellow" could be associated with negative emotions like cowardice or fear.
To accurately understand what someone means when they say they're feeling "yellow," it's essential to ask for clarification and further context to grasp the specific meaning they intend to convey.
