How Do Photons Create Different Colors of Light?

[gaurav pant]

i have read that light is made up of photons how does similar photons can produce lights of different colours(pardon me if this appears a silly question to u

The color of a photon depends on its wavelength \lambda or frequency f or energy E (take your pick). They're all related to each other:

c = \lambda f

E = hf

E = hc / \lambda

where c is the speed of light and h is Planck's constant.
