Select a color with photoshop
I'm going to click again in the middle of the blue gradient so we can take a closer look at the Fuzziness option and how it lets us adjust our selection on the fly: Clicking again in the middle of the gradient. To switch between the foreground and background colors, click the double pointed bent arrow just above the Color boxes. Click the Foreground Color box at the bottom of the Tools panel to open the Color Picker.
The Color Range dialog box gives us a similar way to set the acceptable range, except here it's not called Tolerance, it's called Fuzziness, and it has a major advantage over the Magic Wand's Tolerance option. On the New Layer window, use the drop-down menu to choose a new background color for your image. If I click on the yellow bar: Clicking on the yellow bar.
I'll choose the first one, Grayscale: Choosing Grayscale from the Selection Preview option. If you're following along, you can use this image, from the practice files for this tutorial. We'll see an example of how Fuzziness works in a moment: The Fuzziness option is the Color Range version of the Magic Wand's Tolerance option.
And this is very useful for changing the color of objects in photographs. We see in the preview window that I've once again selected an area in the middle: Back to the original selection. A much more useful preview option is found at the very bottom of the Color Range dialog box.
Which is just to the right of the left bracket key on the keyboard. And there are many to choose from.
Color, range is a selection command, and we access it from the same place we access other commands - the Menu Bar along the top of the screen. I can also drag across an area, just as we saw with the gradient, to add multiple shades of red to my selection at once: Holding Shift and clicking to select more shades of red. You can use any color you like if you're following along.
Again, we'll see how this works in a moment: The selection preview window. You can also select a different brush tip to change how the brush strokes look. The Swatches panel contains preset chips of color. All four options can be useful ways to preview your selection in the document window.
Likewise, I could have dragged the slider towards the left to lower the Fuzziness value, in which case less of the gradient would be selected: Increasing the Fuzziness value with the slider increases the selected area in the preview window. This isn't a huge problem, just something to remember: The standard "marching ants" outline is now displayed around the selected part of the gradient. The preview window updates to show me that I've now selected a lighter part of the image: Lighter shades of blue are now selected. This adds a Black White adjustment layer above my image on the Background layer.
To switch back to viewing the image, set the Selection Preview option back to None. To access the Subtract from Sample Tool from the keyboard, hold down your Alt (Win) / Option (Mac) key, then click on the image to remove an area from the selection.
