The new Point Color feature in Adobe Camera Raw enables more powerful and precision color editing than even before. In this video you’ll learn how to use Point Color to make adjustments based an all three dimensions (Hue, Saturation, and Luminosity). While Point Color is designed to be easy to use (you can simply sample a color and start making adjustments), this in-depth video also points out key differences between Point Color and Color Mixer and demonstrates how to use the range sliders to achieve the exact color adjustments that you’re after. Point Color is available both when making edits to the entire image and when adjusting only a portion of an image using masking In Adobe Camera Raw.
Two additional points that I believe are worth mentioning: the order of the Point Color samples matter. As additional Color Point samples are added, they effect any Colors that have been previously adjusted in the image. And, as more and more samples are added, if the samples are close together values, the reach of a given range value on the slider may contract, so fewer colors will be affected than if there were only one sample of those values. This allows each color a distinct area without blending them all with less visible effects.
