Exercise Four:
Color in Map Symbol Design

Introduction & Objectives

Lesson 4 has discussed and demonstrated ways to use color to represent different data types on maps. It was demonstrated that the color dimensions of hue, value and chroma can be manipulated to create color that is representative of the data. The objective of this exercise is to select/create representative color for each data set found below. You will also be referring to Brewers Color Guidelines for selecting color for relevant data sets.

Design color to represent each of the following data sets.
Select the color from Tables 1 and 2, where indicated.
Enter the Row,Column number from the table in each space.
For Part 2, use the linked Java Applet to create colors representative of the data sets. Place the percentages of CMYK per color in the appropriate form boxes.
Where needed, e.g, when using black for the darker hues, create color using Adobe Illustrator (or equivalent graphic software), and place the percentages of CMYK in the appropriate form boxes.

Subject, e.g., Exercise Four:

Part 1 - Color in Single Variable Symbol Design

In this section you will select colors from Tables 1 and 2 for answering Questions 1-3. (Note: Table 2 represents the CMYK combinations for creating color in the same boxes within Table 1, e.g., A1 is 100% Yellow in both tables. Also, "K" stands for Black).
Select colors from Table 1 and 2 to represent each data set below. Give the appropriate Row and Column identification in each space provided, e.g, A2, C5, G3, etc.
Where required, link to Brewer's Color Guidelines and answer the appropriate questions.

Question 1a: Select colors for the following Landcover/Landuse categories: (9 marks)

a. Residential
b. Commercial
c. Industrial
d. Recreation/Parks
e. Forest and Forest Products
f. Subsistance Agriculture
g. Crops and Livestock
h. Nomadic Herding
i. Barren/Open Space

Colors (Row, Column)

Question 1b: Go to Brewer's Color Guidelines and determine into which category(ies) the data will fit. Indicate the data type(s) here (2 marks):

Question 2a: Select colors for the following Religion categories: (10 marks)

a. Christianity
b. Judiasm
c. Catholicism
d. Islam
e. Hinduism
f. Buddhism
g. Shintoism and Buddhism
h. Confucianism and Taoism
i. Indigenous Religion
j. Other, mixed, none

Colors (Row, Column from Table 1 or 2)

Question 2b: Go to Brewer's Color Guidelines and determine into which category(ies) the data will fit. Indicate the data type(s) here (2 marks):

Question 3a: Select colors for the following Export Earnings categories: (6 marks)

b. 15.0 - 19.9
c. 10.0 - 14.9
d. 5.0 - 9.9
e. 1.0 - 4.9
f. 0.0 - 0.9

Question 3b: Go to Brewer's Color Guidelines and determine into which category(ies) the data will fit. Indicate the data type(s) here (2 marks):

Part 2 - Color Selection for Single or Multiple-Variable Symbol Design

In this section you will use a java applet to create colors to represent a series of data sets. Some of these data sets are single variable, while others contain two variables. In the case of two variables, you are required to create design solutions that use color for both variables as is demonstrated in Brewer's Color Guidelines. As above, you will also be required to describe where the data fits into Brewer's schema of data variable types.

Instructions:

Read all instructions carefully before starting.
Create a relevant color series for each of the data sets below using the CMY process color mixing java applet (Java Applet created by Phillip Dukes of Bringham Young University, email: g-prd@physics1.byu.edu)
To create colors, select the Color Printing section of the java applet, modify the percentages of cyan, magenta and yellow by using the up and down arrows, then drag and overlap the squares to form the color.
Write the percentages of CMYK for each process color in your graded series. Note that there is no Black in the java applet; you may therefore wish to refer to a color chart or use Adobe Illustrator, or equivalent graphics software to create the darker color(s) in your graded series. In all cases, note the percentages of CMYK in the appropriate spaces. Enter 0 when no color is used, e.g., 50 C, 60 M, 0 Y, 0 K.
