No, you idiot, he's just proven colour is proportional to

You're talking about Wein's Displacement Law, derived
from the blackbody radiation curve (as I recall, you
don't believe blackbodies have anything to do with
temperature).

The relationship between peak wavelength and
temperature is:

lambda*T = 2.9*10^-3 m*K

The relationship above gives

lambda*T = (c/f)*T = hcT/(0.5kT)
= 2hc/k
= 0.029 m*K

Right proportionality, but off by a factor of 10. The
resemblance to the actual relationship (Wien's Law)
is purely accidental, since there is no physical
basis for equating those two energies.
