I am looking at incorporating colours into some templates for
OpenOffice eBook templates and have come across the concept of a
colour (color) wheel. The idea is that colours (colors) that are
opposites on the colour (color) wheel should be used to contrast to
one another.
Has anyone ever developed a colour (color) wheel using the standard
colours (colors) and names of colours (colors) from the OOo standard
pallete? I do not want to complicate things by getting other colour
(color) pallettes.
Alas, color space (as perceived by most human beings) is
three-dimensional, not two, and shaped more or less like a cylinder.
(Four-dimensional, if you include a transparent-opaque axis.) And the
axes aren't linear, either.
There's a reason that color matching is a billion-dollar industry.
Also, a lot of colors actually employed use three visible colors, that
is some red, some blue, and also some green in varying quantities. Such
colors can’t be shown at all on the standard two-dimensional color
wheel, unless you want to grade from pure color to third color mixed
rather than from dark to light.
No matter what you do, you will be missing some colors or hues.
