Many people are familiar with using curves for adjusting contrast and tonal values, but we can also adjust colour with curves in a very nice way. By selectively adjusting the RGB channels we can quickly emphasize or de-emphasize colour and take more control of how it appears. This isn't colour-correction: we're not making pictures appear neutral. Instead, we're going to use colour to add mood to a scene. In this tutorial, you'll learn how to creatively and expressively adjust colour with Tone Curves in Lightroom.
In our example, however, we do start with a colour-corrected, normalized image, as above. The picture looks fine: contrast is good, we've adjusted the white balance to a neutral point, and there are no big pre-exisiting colour casts in the image. Evaluating a "not-to-anything" image lets us decide what aspects of the picture we want to bring out with colour.

Colour is a powerful expressive tool when used with care. Take caution,
though, colour can also overpower all the other aspects of a photograph.
Controlling and adjusting the colour in your image is a delicate
balance. When adding colour effects to your images you want to avoid
simply washing the whole image with your colour of choice and instead
apply the adjustment purposefully and selectively.
