Using Visual Elements: Background, Color, and Text 139
It’s possible, but extremely challenging, to create diagrams in a palette with only two colors.
Adding black sparingly helped emphasize important points by increasing the contrast.
For diagrams and illustrations, the designer needed to
select additional colors but use them sparingly. The two
colors in their existing palette plotted on the wheel as
almost an analogous palette because they’re so close
on the color wheel. We used those colors as a starting
point. In an effort to continue to constrain the colors for
dramatic appeal, we decided to keep all the colors on
one side of the color wheel and select every other color
on the wheel (in various shades and tints). We made sure
that the new colors played a secondary role to the two
colors in the core palette. Beware of visually overwhelming
your audience by giving equal value to all colors.
Here’s how the palette
plots on the color wheel.
Selecting colors from one
side of the color wheel
ensured contrast and
color harmony.
