HUE: One of the main colour attributes apart 4rm the lightness and colourfulness of an image,hue is associated wit the colour red and yellow: so when the hue is edited, its like putting a film of coloured plastic over the image.

Saturation:Defined by the intensity of color. When it is high, colors appear vivid and vibrant; when it is low, the colors take on a darker tone. If it's too high, the image becomes Vibrant in a psychedelic way
Brightness:the amt of light given off by an object.Brightmess is subjective:it depends on the eyes' sensitivity to light.
Luminance:The measurable component of brightmess. So the luminance of a bulb is the same whether it's measured from 3 or 12 meters away.
Contrast:A combination of colour and brightness(woe!),contrast refers to the visual details of an image that distinguish objects in the foreground 4rm those in the background. If an image has a lot of details but wit low lighting, increasing the contrast will improve it.
Usage:So i got this shot of a king cobra, hood raised..right in front of me!No, really! But u couldnt see the spots.. So i tweaked the contrast.. And i had 2 increase the brightness.. Actually the luminance was what needed adjustment, and the saturation, too.. Those colour! It got a yellowish hue, which i m not touching.
