Colour Range<br />
As an intelligent colour selection method, i.e. where selection is based on “tagging”<br />
a specific range of colours in the image, choose the Colour Range command.<br />
To select a colour range:<br />
1. Choose Colour Range... from the Select menu. The Colour Range dialog<br />
appears, with the image visible in the Preview window.<br />
2. To make an initial selection:<br />
• To tag a particular colour group, such as "Reds" or "Midtones," choose the<br />
group’s name from the Select drop-down list.<br />
OR<br />
Click the Colour Picker button to reset the adjustment and then<br />
drag across a section of the image in the Preview window to tag a colour<br />
range. With this method, the Tolerance slider lets you include a wider or<br />
narrower range of colours in the selection.<br />
Once you’ve made an initial selection, you can use the Add Colour and<br />
Subtract Colour buttons and drag to tweak the tagged range.<br />
Meanwhile, the dialog provides visual feedback.<br />
1. If Show Selection is checked, the greyscale Selection window on the right<br />
shows tagged values as brighter, with untagged pixels darker. To customize<br />
what’s displayed in the Preview window on the left, choose an option from the<br />
Preview list: "None" shows the original image, "White Matte" shows tagged<br />
pixels through a white background, and so on.<br />
2. Click OK to confirm the selection, or Cancel to abandon changes.
