Using Color in Flower Gardens
Introduction to Color
There is no right or wrong when it comes to color in the garden. Color choices are a matter of personal taste.
For some, a riot of color is just the ticket.
Others prefer to work with a simpler palette.
Understanding the basics of color theory (which artists often use to guide them when
they mix paint) can help explain why certain combinations work for you, and why others
don't. It can help you combine different colors of blooms, foliage and other elements in
ways that you find pleasing.
Don't limit your color thinking to just blooms. You have extensive color choices with
foliage, too. Beyond the many shades of greens, foliage comes in countless yellows,
reds, blues, grays, and earth tones. Bark, buds, fruit and other plant parts contribute to
your palette, as well.

Use color on structures for interesting effects. Split rail fences, arbors, seating,
structures and enhancements don’t have to be dull brown or black. Painted pots and
boldly colored window boxes can complement or contrast with plantings. A vivid blue
bench, brightly painted birdhouse or purple dog house can liven up your landscape.

Keep in mind as you plan that most landscape and garden designers agree that color
schemes are more effective when you use large masses of color, and not single plants or
blossoms in a scheme. Group plants in drifts for maximum impact.
Warm Colors
Let’s start with a simple color wheel which is essentially the colors of the
rainbow arranged around a circle. Note that on one side of the wheel are
what we call warm colors -- yellows, oranges and reds.

Warm colors (reds, oranges, and yellows) catch your attention. They are
lively and energetic.
[+] larger image
Warm colors appear to come forward in the landscape, and seem closer
than they really are. They make big spaces feel smaller. Use them to draw
the eye toward features you want people to notice or away from eyesores.
Here, your eye follows the yellow flowers to the trees in the background,
de-emphasizing the buildings on either side.

Keep in mind that each color -- whether warm or cool -- has a range of
warmness and coolness. The effect of these vermilion blooms -- an
orangish red -- is far hotter…

… than the reds in these flowers, which are more toward the violet end of
the spectrum.
Cool Colors
On the other side of the wheel are the cool colors -- greens, blues and
purples.

Cool colors (violets, blues, and greens) appear to recede in the landscape.
They seem farther away than they really are, and can make small spaces
feel bigger.
[+] larger image
Cool colors have a calming, soothing effect.
[+] larger image
If your flowers are mostly warm colors and you want to soften their
intensity, consider adding some cool-color blooms and foliage to provide
contrast. Here, the fiercely hot orange celosia is cooled by the purples of
surrounding blooms.

If you garden in a small space, using cool colors will make it seem bigger.
Color Wheel
Taking a closer look at the color wheel, you can see a triangle made up of
the three primary colors -- red, blue, and yellow. They are called primary
because they can't be made by mixing other colors together.
Between the primary colors on the wheel are secondary colors, which are
made by mixing two primaries:
orange = red + yellow
green = yellow + blue
violet = blue + red
Going one step farther, there are tertiary colors, such as blue-green and
yellow-orange, between the primaries and secondaries, and an infinite
spectrum of colors between those. In our gardens, we find more of these
types of colors than the "pure" primary and secondary colors. (Artists also
use the term tertiary colors to mean colors created by mixing all three
primary colors to produce many of the colors found in nature from mustard
yellow, browns -- from yellowish to reddish to deep umber -- and finally
black.)

A full color wheel that shows more of these gradations is a closer
representation of the spectrum of colors than the simple one we’re using to
understand the basic concepts.
Color Complements
Complementary colors are located directly opposite from each other on the
color wheel. (Follow the black lines that go through the center of the
simple color wheel.) For example:
Blue complements orange.
Green complements red.
Yellow complements violet.
Because the secondary color in each complementary pair is made up of the
other two primary colors, you can think of these combinations as having all
three primary colors. The complements "complete" each other.
[+] larger image
When used together, complementary colors intensify each other. Red
flowers, for example, look brighter against a green background.

The red foliage of the coleus makes the green moss stand out.

When yellow and purple flowers bloom in close proximity, the whole effect
of these complementary colors is greater than the sum of its parts.

Blue looks more striking in close proximity to its complement, orange.
Analogous and Adjacent Color

To avoid jarring combinations use analogous or adjacent colors -- colors near
each other on the full color wheel.
[+] larger image
Analogous combinations harmonize or blend together. In this example, we have
the yellow flower, the yellow-green leaf margin, and the green leaf interior
represent all colors found close to each other on the color wheel.
[+] larger image
If using three adjacent colors, try using the middle one as the predominant color, and the others on
either side of it to a lesser extent. Here, blossoms on the bluish side and reddish side of violet are
subordinate to the violet blossoms.
When using analogous colors, try keeping their intensities the same. Intensity refers to the
amount of gray an instance of a color contains. An intense or saturated color has little or no gray.
Desaturated colors (called tones) have more gray added, and appear muted.
Monochrome
[+] larger image
Even simpler than combining adjacent colors is to use a monochromatic
theme, which focuses on just one color, here yellow.
[+] larger image
The monochromatic "moonlight garden" features all white blossoms that
are particularly attractive at dusk or at other times when light is low.
Differences in plant form and texture become more pronounced in the
monochromatic garden as the garden deemphasizes differences in color.
Color Variety
[+] larger image
The triad theme uses three colors evenly separated on the color wheel,
such as all three primaries (red, blue and yellow) or here, the three
secondaries (violet, orange and green). Using triads in full intensities yields
a very vibrant, energetic harmony.
[+] larger image
Another strategy is the split complementary theme: Start out with a
complementary pair, such as yellow and violet. But take one of the colors
and use the colors close by on either side on the full color wheel. In this
case, the yellow flowers in the foreground form a split complementary
pairing with the reddish-violet and bluish-violet flowers in the background.
Shades and Tints

Another aspect of color involves adding white or black to pure hues.
Adding white lightens color, and the result is called a tint. Adding black
darkens the color and the result is called a shade. For example, pink is a
tint of red and maroon is a shade of red. Note the full color wheel includes
increasingly lighter tints toward the outside and darker shades toward the
center.
[+] larger image
Shades -- in this case a rather dark shade of yellow -- have a low-key
effect, making the scene more somber. Their color holds up in the middle
part of the day when there is plenty of light. But they fade toward black as
light decreases in the evening.
[+] larger image
Tints--in this case the lighter yellows in the foliage and flowers -- have a
brightening effect. When the sun is high and unobscured these plants may
appear washed out, but later in the evening they will remain evident when
the darker shades have disappeared.
Neutral Color
[+] larger image
In addition to the colors on the wheel, you can make use of neutral colors -- black, white, and gray -- and earth
tones such as brown, tan and olive to create certain effects. All make good backgrounds to accentuate other colors.
Here, a dark background makes the foreground appear lighter. Lighter backgrounds will appear to darken blooms in
the foreground.

Here, the dark grass, earth, and shadow in the foreground accentuates the lighter foliage of the shrub.

You can use neutral colors as "punctuation" in the garden. Here, gray foliage plants and white flowers are useful to
help separate combinations of plants using different color schemes.
[+] larger image
White flowers or foliage with white variegation are especially good for lightening up dark, shady areas.

Yellows and light tints of other colors do the same.
