The circadian rhythm, or "body clock," is influenced by external cues, or "zeitgebers," such as light. Different wavelengths of light (which we perceive as different colors) can have different effects on this rhythm.

1. Red light: This has the longest wavelength and least energy among the three colors. It has the least impact on the circadian rhythm and is less likely to cause a phase shift.

2. Green light: This has a wavelength and energy level in the middle of the spectrum. It has a moderate impact on the circadian rhythm.

3. Blue light: This has the shortest wavelength and most energy among the three colors. It has the greatest impact on the circadian rhythm and is most likely to cause a phase shift.

So, blue light will cause a larger circadian phase shift compared to red and green light.
