What colour or wavelength are human's eyes most sensitive to?

what colur or wavelength is humans eye most sensetive to.

and cud any one define hue and saturation

thanx

There is a lot of evidence that green/red is genetically most sensitive color in humans and related primates.

Hue is the quality of a color as determined by its dominant wavelength.

Saturation is referred to chromatic purity: freedom from dilution with white.

Green for sure is the most sensitive.
Red and blue are at the edge and not so sensitive.

Mandi

Human eye is sensitive to RGB accoding to the equation
0.30 R + 0.59 G + 0.11 B

The monitor is also made to fit this equation. And most of the imaging softwares also use the same algorithm to convert a color image to graylevel.
