3. Select the Eyedropper tool and choose Point Sample from the Sample
Size drop-down menu on the options bar. Drag the eyedropper slowly
outward from the center of the color wheel and observe how the slid-
ers in the Color panel change. Color saturation ramps up until you
reach the ring of full saturation and brightness. Brightness ramps
down to black as you continue sampling color out to the edge of the
color wheel. Hues change around the wheel, while analogous colors
surround every point and complementary colors are on the opposite
side of the wheel (see Figure 4.7).
point samples
measure the color
of individual pixels.
Larger sample sizes
take the average
color of grids of
pixels, which can be
useful when sam-
pling photos.
