    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

    Development (including information

    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.
