The typical human eye is most sensitive to which primary colour?

Thanks for any help

The normal eye is supposed to be equally sensitive to all three primary colours, red, green and blue.
But colour-blindness, even to a very small degree, occurs often in red and green but never, apparently, in blue. So that might be the answer

Not quite accurate, as the the wavelength of light perceived as brightest to the human eye is 555 nm, a greenish-yellow colour (http://www.tedmontgomery.com/the_eye/retina.html)

Green I think

Thanks for them, I think I will go with green

We've had this before and I don't know the answer but green is NOT a primary colour (a mix of blue and yellow).

Strix - you're confusing paint and light!

Quizmonkey,

Mea culpa, you're right and for anyone else who wants a more definitive answer about primary colours see:

Which colour the retina is most sensitive to is another question, depending on day or night/rods and cones/visual purple - hence the different colours used by the emergency services.
