Hues are basically the Primary and secondary colours (Rainbow colours)that one have on the colour wheel , such as Red, Green , blue etc.. Secondary hues are the colours that we create by mixing the primary hues.
Hues are measured in degrees , from 0 to 359 degrees.
Saturation -
If an image has low saturation it will be as if it is washed - out whilst on the other hand , if the image has high saturation the colours will be more vibrant and pure.
An example in the image below shows the last image with washed out colours , which means low saturation settings are set (-50)whilst the middle image has higher saturation settings (+50) and is making the colours more clearer and vibrant. The first image is the original image.
