This question has a real subtlety in it.
The simplest answer is given by Wein's Law, sometimes called Wein's Displacement
Law:
The peak of the spectrum for any "blackbody" (this works approximately for
stars and people, basically any opaque object).
Wavelength of peak emission = (Stefan's constant, which you can look up) x 0.0029meter / temperature in Kelvins.
According to this formula, the peak is in the green part of the spectrum.
But a lot of light is given off across the visual part of the spectrum so it looks
whitish to me.
Here's the subtlety that few people realize. This all works only when you plot
the spectrum as the emission per unit wavelength. You can also plot the emission
per unit frequency. Then the peak is at a different location!

Will people be affected by electromagnetic radiation?
that depends on the wavelength of the radiation. the shorter the wavelength the more damage it can do.
What is the smallest infrared radiation wavelength?
the smallest infrared radiation wavelength is ranging from 0.75-1.3micrometre
Is the UV radiation the sortest wavelength?
No, gamma rays have the shortest wavelength.
What type of em radiation has shortest wavelength and most energy?
Gamma radiation
What is the relationship between the color of the star and temperature of a star?
The color of a star is related with the wavelength of the light observed. Wien's Law states that: Peak Wavelength x Surface Temperature = 2.898x10-3 Peak Wavelength is the wavelength of the highest intensity light coming from a star.
What is important about the peak wavelength of a thermal radiation spectrum?
The peak wavelength, is connected to the temperature of the objects. we have short peak wavelength when the temperature is high.
What is the peak to peak distance of a wave?
The wavelength.
What is the peak to peak distance of wave?
The wavelength.
How do you label a wavelength?
you label a wavelength with amplitude, wavelength, through, and peak.
What is long wavelength radiation given out by stars?
Infrared radiation is long wavelength radiation given out by stars.
What are the four parts of a wavelength?
the four parts of a wavelength are the peak, trough, wavelength, and the amplitude.
What is described by the wavelength of wave?
The distance from on peak to the next peak
Will people be affected by electromagnetic radiation?
that depends on the wavelength of the radiation. the shorter the wavelength the more damage it can do.
What is the smallest infrared radiation wavelength?
the smallest infrared radiation wavelength is ranging from 0.75-1.3micrometre
Radiation with a wavelength 4.2 nm?
X rays have a wavelength of 4.2 nm.
Because c the speed of electromagnetic radiation is a constant the wavelength of the radiation is....?
The wavelength is inversely proportional to its frequency. That is, as the frequency increases, the wavelength decreases and vice versa.
Is the wavelength the distance from the crest to trough?
The peak-to-peak amplitude is the distance from the trough to the crest. The wavelength is the distance from one crest to the next crest.
