Many sales presentations could be improved by using the color wheel that PowerPoint and Keynote incorporate , but most of the people do not know it.

1. The Colour
Authored by: Jean-François MESSIER

2. How does the
work?
The colour wheel
was discovered by
Sir Isaac Newton.
The color wheel
allows you to create
colour palettes that
match and are
consistent.
You can create
palettes based on
several types of
effects.

3. Monochromatic
You select colours
in the same
segment, but nearer
or farther from the
centre.
Using variations of
the same colour can
create a striking
palette, but it’s
difficult to use Example
colour effectively
without adding
black, white, and
shades of gray for
contrast.

4. Analogous
Selecting colours
that are touching in
the wheel creates a
narrow, harmonious
colour scheme.
Similar to
monochromatic
colours, analogous
colours provide a
predominantly
warm or cool Example
feeling, depending
on where they lie on
the wheel.

5. Complementary
Colours from the
opposite ends of
the wheel provide
the most contrast.
If you can resist the
temptation to add
more colours, limit
yourself to just two
to create a powerful
(or even startling) Example
look.
But arrange them
wisely so they don’t
clash.

6. You can also opt for
a 3-colour harmony
Split Complementary
that alternates two
cold colours and
one hot one, or the
other way around.
This variation of the
complementary
scheme uses two
colours on either
side of a directly
complementary
colour. Example
These colours have
high visual contrast
but with less visual
tension than purely
complementary
colours

7. Triadic
Three colours
equally spaced
around the colour
wheel create vivid
visual interest.
Some palettes are
bold while others
are more refined.
You can modify this
method by using a Example
light tint or dark
shade of one of the
three colours
instead of the pure
hue.

8. Tetradic
This scheme is Tetradic
popular because it
offers strong visual
contrast while
retaining harmony.
It uses two pairs of
complementary
colours.
It’s difficult to
harmonize this
scheme if all four
hues are used in Example
equal amounts.
Pick a dominant
colour for your
design and use the
others to support
the main one.

9. Microsoft’s PowerPoint colour picker
PowerPoint and
Apple’s Keynote
applications base
their colour wheels
on the one that Sir
Isaac Newton
discovered.
The wheel uses
three primary
colours, red, yellow
and blue, spaced
evenly apart.
Blending those
colours creates the
full colour wheel, as
shown here.
