AP187 Act5: Measuring the Gamut of Color Displays and Prints

In this activity, we determine the gamut of certain devices: a dell and an hp laptop and a projector. We displayed red, green and blue from these devices and determined their CIE xy coordinates.

Figure 1: Gamut of a dell laptop, an hp laptop, and a projector

In figure 1, the gamuts (the triangles in this case) of the devices are displayed in the CIE xy. If we compare the areas of these, the largest one would correspond to the device which can display a larger range of colors. At first glance, the gamut of the hp laptop seems to have the largest area and therefore can display a larger range of colors.
