03 Change the hue
If I drag the outer end of the control bar in a clockwise direction, I can shift the hue of the target colour. Here, I’ve moved it from the lilac section of the hue wheel into the the blue section. You can see the difference it’s made in the ‘after’ shot on the right.
04 Change the saturation
You’ll see the control bar also has a slider/button part of the way along it – you drag this outwards to increase the saturation, which is what I’ve done here, or inwards towards the centre to reduce the saturation.
Now that I’ve increase the saturation, it’s pretty obvious that the tool has modified the colours to some degree across the whole image, not just for the targeted colour. This isn’t how the tools in other programs work, so while it may be a deliberate attempt to make global hue changes simpler, it is slightly disconcerting.
05 Limiting the effect
There is a simple way to refine the colour selection, though. You simply add another Multi-Point Color Balance tool to an area which you don’t want to be affected. You don’t need to make any adjustments to this – it has the effect of protecting that area and neutralising the effect of the previous adjustment. I’ve added a new Color Balance tool to the background just to the right of the car, and you can see this has restored the colour and tone of the original picture.
