RGB values are often stated as HEX values. HEX is short for hexadecimal (or
base 16). The hexadecimal system uses the following digits: 0, 1, 2, 3, 4, 5,
6, 7, 8, 9, A, B, C, D, E, and F. The letter digits have the following
values:
The GIMP's dialog box for color selection displays the HEX values for the
color you select. If you use a slider for R, G, or B the resulting value is
displayed to the right, BUT at the bottom the HEX TRIPLET is also displayed
and automatically updated.

ASSIGNMENT: For this assignment you will create a six column
table. Your column headings will be COLOR_NAME, RED, GREEN, BLUE, HEX TRIPLET, and
SAMPLE. Under the RED, GREEN, and BLUE columns you will place the decimal
value for that component of the color (the name of which will appear,
obviously in the COLOR_NAME column). The HEX TRIPLET column will hold the six
digit hex values. The SAMPLE column will hold small sample images for each
color included in the table. Here are the colors you must use: red, green,
blue, yellow, magenta, cyan, and purple. You must set the background color
for your page to white (using HEX values). You must create your sample
images in The GIMP. They will be small squares of one color. You will save
these images as JPGs.
