Question

Colors are produced by changing the intensity of the red-R, green-G, and blue-B pixels. What color would the following represent? (The number in the parenthesis measures the intensity of the color)
1. R(100), G(0), B(0)
2. R(100), G(100), B(100)
3. R(0), G(0), B(0)
4. R(100), G(0), B(100)

Answer 1

Hmm

1. R(100), G(0), B(0) -> Red
2. R(100), G(100), B(100) -> Grey
3. R(0), G(0), B(0) -> Black
4. R(100), G(0), B(100) -> Violet

Note: Color intensities occur in the range from 0 to 255 (or 2^8-1)

Answer 2

Assuming 100 means 100%:

1. Red

2. White

3. Black

4. Magenta

Answer 3

According to Wikipedia's list of colors,

a) Because only red is present, red will be produced

b) Because R, G, B are at maximum intensity, white will be produced

c) Because R, G, B are at minimum intensity, black will be produced

d) Because red and blue are present without green, purple will be produced.
