Colour Theory Part 4

-Small areas of high-contrast colours don't read comfortably. This reduces the readability.
-The same colour can be read in two completely different ways depending on the surrounding colours determining the variation in contrast. For example grey on green can appear as a light lilac whereas grey on lilac appears slightly green.

10 Questions About Colour Theory 

_______

1. What is it that makes someone who's colourblind to perceive colour differently?

2. We have three types of cones. What happens if one of the cones stops functioning?

3. Is there a further term for mixing colour beyond tertiary?

4. Can complementary colours ever work well together?

5. How is the chromatic value recorded?

6. Why/how does our brain perceive simultaneous contrast - why is is sometimes hard to differentiate between colours?

7. If orange and blue are placed together, is this contrast of temperature, complementary, or both?

8. What happens when metallic colours are placed together?

9. Is the same theory used for fluorescent colours?

As a group we agreed on our 5 best questions for another group to research and answer.
These were:

1. What is the maximum number of colours you should use in a design?

2. Should colour be chosen in natural light or the most appropriate context in which it would be used in?

3. Is it ever appropriate to use complementary colours (and why are they called complementary colours)?
4. How can colour theory be applied to metallic colours?
5. Should a different colour theory be applied for on-screen/RGB?

-CMYK in print is usually paid for as four separate plates: cyan, magenta, yellow and black.
In other words this means thats CMYK uses a 4-colour process.
-When using a linen tester, CMYK appears dotted.
-Formula based prints = no dots
-Each plate (CMY+K) are all very different from one another as shown below:

Cyan

Yellow

Magenta

Black

C+M+Y+K

5 Questions to answer as a group:

1. Why do colours force out complementary colours?

2. What is the simplest way to balance colour?

3. Is it always a case of contrast of and hue working together?

4. What is the recommended amount of colours which can be used?

5. If everyone perceives colour differently does this mean we perceive contrast differently?

5 Questions answered:

1. When two colours are mixed together, they produce a pale grey.

2. The simplest way to balance colour is 10%, 60%, 30%

3. Yes tone and hue always work together.

4. You can use as many colours as preferred, however there is a greater chance of using too many rather than too little (too many colours looks too busy).

5. No people don't necessarily perceive contrast differently?
