“I saw the dull yellow eye of the creature open”
Context: On a "dreary night of November", Victor witnesses his creation come to life.
Analysis
The clinical, anticlimactic detail of the "dull yellow eye" instantly deflates the grandeur of Victor's ambition — the longed-for triumph becomes repellent reality. The jaundiced "yellow" colour connotes sickness and decay, undermining any sense of beauty or success. Shelley uses the moment to mark the collapse of Victor's dream into horror, beginning his abdication of responsibility.

Exam Tip
Pairs perfectly with "breathless horror and disgust". Use for the gap between ambition and consequence, and Victor's instant rejection of his creation.
