Hue, saturation, and lightness palette

This palette adjusts the image in reference to the HSB color model. These controls can be used to
manipulate the color image rather than producing a realistic representation.
The HSB color model defines color based upon human perception rather than photographic process-
es. Hue refers to each separate color in the model. Saturation is how vivid each color is. Lightness
describes how bright or dark a color is in the color space.
The hue control is not a color balancing tool. It is a creative tool. When changing hue in the palette,
each color is assigned a new hue depending on the degree of rotation through the color space. For
example, a very simple color space could have three colors: red, green, and blue. I have a red barn
next to a green tree with a blue sky. Now I rotate the my image in the color space; the colors are
reassigned a new hue based on the position - the barn is green, the tree is blue, and the sky is red.
The HSB color space is similar, but with many more hues.
Unlike the brightness control in the brightness, contrast, color balance palette, the lightness control
does not change the apparent density of the colors equally. For example, with an extreme increase in
lightness, blue will not appear as light as yellow.
