Question 1. Figure 2A is a picture of model trucks and cars.
It is desired to change the color of the bulldozer from yellow to green.
Using the Hue/Saturation adjustment seen in Figure 1, the Edit drop down box was
changed to Yellows. Then the eyedropper tool, circled in red in Figure 1,
was selected and clicked on the bulldozer only. The Hue slider was then
moved to the right until the desired color was achieved. In this case,
+62. However, as seen in Figure 2B, the car was also changed to green.
Why did the color of the car change when the eyedropper was only clicked on the
- The eyedropper tools are color range selection tools. When
used, they will set the color range to be changed and all
pixels in the image that fall in the selected color range will be
changed. To limit the change to the bulldozer, a selection would
have to be made around the bulldozer.
Question 2. Figure 3A shows the six color ranges listed in the
Edit drop down box for the Hue/Saturation adjustment. The color ranges are
reds, yellows, greens, cyans, blues and magentas. In Figure 3B are three
color chips. Chip 1 is turquoise. Chip 2 is brown. Chip 3 is
True or False. Since the colors turquoise, brown and purple are not listed
in the Edit drop down box, Hue/Saturation will not be able to work with these
- False. Turquoise falls within the cyan color range.
Brown falls within the red color range. Purple falls within the
blue color range. Fortunately, we are not required to memorize
which of the six color ranges a particular color falls into. The
easiest way to select by color range is to use the eyedropper
tools. To do this, click the down arrow of the Edit drop down box.
Select any color range, except Master. Click the left most
and click on the color in the image that needs adjusting. Photoshop
will automatically reset the Edit drop down box and the Color Range
Boundaries to the correct color range. To select additional colors,
click the + eyedropper
and click in the image.
The figure below shows what the Hue/Saturation dialog box looks like
after the eyedropper tool was clicked on the purple color chip.
