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
