The physics of color The human eye can see electromagnetic radiation at wavelengths between 400 nanometers (purplish blue) and 700 nanometers (red). This range is called the visible spectrum of light. We see pure spectral light as intensely saturated or pure colors. Sunlight at midday, which we perceive as white or neutral light, is composed of light from across the visible spectrum in more or less equal proportions.

Desktop Color Primer
This appendix covers concepts that are basic to printing in color, including:
•
Properties of color
•
Printing techniques
•
Effective use of color
•
Raster images and vector graphics
•
File optimization for processing and printing
If you are already familiar with color theory and digital color printing, you can skip to
the last section (
“Optimizing files for processing and printing”
on page A-16) for tips
on optimizing files for printing.
The properties of color
This section introduces concepts that are basic to color theory. You will encounter
some of these concepts (such as hue, saturation, and brightness) when you work with
color in applications; others provide useful background information.
Color is a complex
topic, so consider this a starting point for experimentation and further research.
The physics of color
The human eye can see electromagnetic radiation at wavelengths between
400 nanometers (purplish blue) and 700 nanometers (red). This range is called the
visible spectrum of light. We see pure
spectral light
as intensely saturated or pure
colors. Sunlight at midday, which we perceive as white or neutral light, is composed
of light from across the visible spectrum in more or less equal proportions.
