It is becoming increasingly normal for
retailers and branded apparel compa-
nies to use digital communication as a
means for both the design and develop-
ment process and the merchandising
process. This leads to a critical need to
be able to accurately define color at the
beginning of the design process andthen consistently and accurately com-
municate color throughout every stage
of design, development, and merchan-
dising, both internally and externally.
As such, we must acknowledge the
need to control color throughout the
entire apparel process requires taking
into account many factors: observers,
illuminants, color standards, display
devices (monitors, paper and/or fabric
printers), production needs, consumer
marketing (catalogs, Internet), etc.
COLOR DEVELOPMENT
The color development process for
apparel retailers and branded apparel
companies will vary greatly depending
on the organization and emphasis at
each company. Selection of colors to be
produced for a season may be a trend
or a design function. Once the colors
are selected, a standard for each color is
produced in sufficient quantity for dis-
tribution to suppliers who must match
the color to the satisfaction of the re-
tailer/brand. This is referred to here asthe color approval process, which entails
at a minimum the following steps:
Send standards with appropriate
instructions to selected suppliers for
color matching.
Receive lab dip submissions from
suppliers.
Evaluate lab dips for color match.
Approve or reject with comments to
supplier.
Communicate with designers when
acceptability of color submissions is
in question.
Track progress of color approvalsand administer the lab dip process.
Consistent Information Needed
Once production orders are placed, the
same organization may receive and
approve production lot submissions.
Depending on the retailer/brand organi-
zation, responsibility for the color
approval process may be assigned to
individuals within the design depart-
ment or to individuals in other depart-
ments. These departments are given
various names, including color office,product integrity, quality control, qual-
ity assurance, or color management. In
some cases, the color approval process
may be outsourced to testing labs.
Concurrent to the color approval
process, design and development must
begin for the graphic design, textile
design, and silhouette design. It would
then seem logical that the same color
standards that are initially communi-
cated
exter-
nally to
the suppliers
for color match-
ing should also be communi-
cated internally for the design processes.
Traditionally this has been done via
small swatches that are then either en-
tered via spectrophotometer into thedesign CAD systems and/or matched
visually via RGB on the CAD. In every
case the same process was being initiated
at least two times in two different chan-
nels within the same company.
With the advent and acceptance of
digital color measurement devices in the
first step of the process, it is now possible
to communicate this initial digital color
information to other steps of the process.
Ideally, the color should be communi-
cated at every step throughout the follow-
ing stages of the product life cycle: Design

concerning the status of lab dip
approval)

Retail
This necessitates coherence between
several different color spaces, color
profiles, and output processes. Devices
in RGB, devices in CMYK, devices
with unique color spaces (i.e., textiledyeing), etc.it is a mind-boggling
proposition. However, there are great
strides being made in this direction.
For the purposes of this article, I will
focus the discussion on the display and
manipulation of color on garments
through texture mapping technology
and 3D rendering.
Spectral data from color standards
are communicated to the design depart-
ments using the information collected
from a spectrophotometer to create a
palette. This spectral data is not trans-
formed for communication, but must be
converted into RGB for monitor display.
Most important is that this display RGB
does not affect printing or output as we
will introduce monitor and printer pro-
files in order to calculate the overlap-
ping color spaces between various de-
vices. For communication to other parts
of the process digitally, we will commu-
nicate in sRGB, CIE-Lab, and/or spec-
tral data depending on the process.
Display and Communication
of RGB
Software packages may not communi-
cate RGB the same way, resulting in
two different values and two different
displays for a single color standard.
sRGB is a standard interpretation of the
RGB color space and enables colors to
be communicated correctly between
software packages. It is a device inde-
pendent color space and will not affect
the display of the colors on various
devices (monitors, printers) when you
use monitor profiles.
Display of Texture MappedImages
The appearance of color is only par-
tially controllable by the new technolo-
gies in place. There are many more
subjective items in the textile and gar-
ment design process.
For example, there is often little em-
phasis placed on the type of lighting used
within the CAD design environment.
Also, a designer will now receive the
color palette from the color standards
creator, but they should not be able to
tweak this color. Here lies perhaps the
most important issue it is not in a
designers makeup NOT to change
things.
Ultimately the color will be applied
to the texture of the fabric for visualsimulation (i.e., a 3D yarn must be col-
ored before being used in a woven fabric
or a knit will be piece dyed with a
color).
The influence of this texture on the
color can greatly change the appearance
of the color in which case, the color that
the designer originally asked for is not
really the color that they intended. Add
to this the application of the colored
textile fabric to a photograph that has its
own unique lighting scenario, shadows,
etc. for merchandising purposes.The intent is that this merchandising
photo will then be communicated either
in the paper form of a catalog or elec-
tronically via the Internet. It becomes
imperative that the color displayed in the
photo is consistent with the product that
the end consumer will finally receive so
as to minimalize any returns to the re-
tailer due to color.
Although there are some challenges
with how the image is to be displayed in
the merchandising process, it can be
clearly shown that there is a value to
allowing a design and merchandising
team to communicate in the medium
where they are most comfortable: visu-
ally. If this is done early in the process
perhaps even before lab dips and/or
productionmany colors may never be
developed due to a lack of knowledge ofhow the color will look on a particular
texture.
CONCLUSION
As technology progresses it will be
necessary for color management sys-
tems to converge with design, develop-
ment, and merchandising systems in
order to properly take into account the
observer, illuminant, and textures when
displaying texture mapped images and
3D rendered garments. This can then be
used to predict the store display.
