Colour Theory

Question 1

Components of colour we can manipulate:

Answer 1

1. ) Hue: Different/various colours
2. ) Chroma: Saturation, intensity, purity
3. ) Value: lightness or darkness

Question 2

Hue:

Answer 2

Different colours!
Each spectral hue has its own wavelength.
we can make millions of more hues by combining percentages of primary hues.

Question 3

Primary colours:

Answer 3

Red, blue and Green

Question 4

Secondary Colours

Answer 4

Magenta, cyan and yellow

Question 5

Value:

Answer 5

The lightness or darkness of a hue.
More light=higher the value
therefore you increase value by removing black.

Question 6

What type of scale does value use:

Answer 6

Gray scale

Question 7

what percentage difference should each value be in order for the human eye to easily differentiate between each value?

Answer 7

15-25%

Question 8

whats another factor in value

Answer 8

Back ground colour!

Question 9

Tint:

Answer 9

add whites to hues (pink is a tine of red)

Question 10

Shade:

Answer 10

Add black to a hue (dark red is a shade of red)

Question 11

Tone:

Answer 11

add equals amount of hue, white and black

Question 12

Chroma:

Answer 12

Also know as the intensity, saturation, richness or purity of a colour.

Question 13

What are the range and what does it mean for chroma?

Answer 13

0% (all gray)-100% (pure hue, max saturation or chroma)

at maximum level the colour appears pure and contains no gray.

Question 14

Do chroma levels differ with varying hues?

Answer 14

Yes! ex.) the most intense yellow appears brighter than the most intense blue-green

Question 15

2 kinds of colour mixing?

Answer 15

1. ) Additive

2. ) Subtractive

Question 16

Additive colour mixing:

Answer 16

combining (adding) primary (RGB) spectral sources of light creates other hues (secondary colors and beyond)
ex.) blue + green=yellow
red+blue=magenta
green+red= cyan

Question 17

Subtractive colour mixing:

Answer 17

By subtracting one primary colours (RGB) the reamining colour is what is perceived. (yellow, abosrobing blue, reflecting green and red.)

Question 18

is additive primary colours or subtractive primary colours darker?

Answer 18

additive primary colours are “darkest”
