Color and Hue Equalizer

Image -> Adjust -> Hue Equalizer

These are PhotoBrush-only inovative tools for adjusting selective saturation or hue.

Color Equalizer
The 16 sliders each represent part of the hue spectrum. Moving slider up will saturate the particular hue and moving it down will desaturate it.
Wit this tool you can selectively (de)saturate or adjust saturation of any color without affecting the others. You can use it for fine adjustement of image (for example saturate more red, without enhancing any other colors) or you can use it for artistic purpose (desaturate all and pick only few colors from hue spectrum for a special effect) - the case below:

Here is the origianl. It has all colors of spectrum. We put down all sliders and then return back only reds and blues. This is the result image, all hue colors except reds and blues are desaturated (black & white)

There are much more way to use it for normal photography - for example you may little desaturate somebody's red face or enhance saturation of green.

Hue Equalizer
Similar in idea to the Color Equalizer. The 16 sliders each represent part of the hue spectrum. Moving slider up will shift the hue from its original value into new.
With this tool you can change color only of particular hue, yet the other colors will stay intact.

Here is the original. Note the cyan car - normally it is too close to blue, by using standard hue tools you would affect also the sky. We moved 2 sliders around cyan color towards pinks-violet. The thin upper horizontal bar represent the original hue spectrum and the bar below represent the new adjusted spectrum The car changed into the violet-pink yet the sky remains unaffected.

Note: The first and last slider both represents the same hue (red) so they move in sync.

Many objects in real life often contains wide area of continual hue (the car on the original is not only cyan, but it has some parts going from green and blue). Sometimes you would need to adjust wider area of hues to change color of an object.

Shortest way rule
The hue is a cyclic parameter. That means you can get from violet to yellow through blue,cyan and green or you can go simply other direction through red. The Equalizer keeps the rule of shortest way. That means if you move slider 8 up to violet and slider 9 down to yellow the transition will go through red, because it is the shortest way.
