Question

I would like to create 545 nm green using the colors in the chromaticity diagram below. What

are the relative fractions of red (X), green (Y) and blue (Z) that will give me that color?

67% red, 23% green and 10% blue

0% red, 100% green, and 0% blue

15% red, 52% green and 33% blue

27% red, 72% green and 1% blue

Some of the ink from a printer has the following reflection curve. What color do we see when we look at the ink?

Magenta

Yellow

Cyan

Red

Referring to the chromaticity diagram above, where are the saturated colors in that diagram located?

In the center of the horseshoe

Along the borders of the horseshoe

All along the bottom of the horseshoe

Nowhere - all of the colors of the horseshoe are unsaturated

A filter serves the function of

Transmitting color(s) from the light which is incident upon it

Adding color(s) to the light which is incident upon it

Reflecting color(s) of light which is incident upon it

Polarizing the light which is incident upon it

Referring to the chromaticity diagram in the diagram again, what is the approximate complimentary color to 770 nm red?

492 nm bluish cyan

380 nm violet

520 nm green

500 nm blue

Referring to the chromaticity diagram, suppose we want to design a computer monitor and define the range of colors it can display by using a color triangle composed of 580 nm yellow, 490 nm bluish/cyan and 600 nm orange. Suppose we now want to watch a football game between two sports teams, one which has red jerseys (say the San Francisco 49ers) and one which has cyan jerseys (say the Jacksonville Jaguars). How will the two teams' jerseys look on the monitor, respectively?

Cyan and blue

White and magenta

Orangish-yellow and cyan

White and cyan

A.

67% red, 23% green and 10% blue

B.

0% red, 100% green, and 0% blue

C.

15% red, 52% green and 33% blue

D.

27% red, 72% green and 1% blue
