Would the night sky appear dark if our eyes were sensitive to electromagnetic radiation with wavelength around 2 mm? Why or why not?

SUMMARY
The night sky would not appear dark if human eyes were sensitive to electromagnetic radiation at a wavelength of 2 mm. This wavelength falls within the range of the cosmic microwave background (CMB), which is the remnant radiation from the Big Bang. The CMB has a temperature of approximately 2.7 Kelvin, emitting radiation that would be detectable by the human eye if it were adapted to this wavelength. Therefore, the sky would exhibit a faint glow due to the omnipresent CMB, making it visibly illuminated rather than dark.
