Colour is one of the most fundamental aspects of textile
design which contributes greatly to the overall visual
effect of a finished fabric. Colour matching is a vital
process in ensuring continuity of colour from the master
standard to all subsequent production batches.
A variety of conditions affect how a color
looks1.Light- source difference
2.Observer Difference
3.Size Difference
4.Background Difference
5.Directional difference
How to Ensure Effective Color in Today's Manufacturing Processes?
The three components of colour matching
There are three components involved in colour viewing,which are LIGHT,
VISION and OBJECT. If any omponent changes, the
actual perception of colour will also change.
It is important to keep the conditions (as mentioned
above) constant when viewing colors.
Colour matching requires the use of a standard light box
which has several illuminants:-

Importance of color Management
Color Rendering of Light Sources
Everybody's perception of colour is slightly different.
Light boxes are therefore employed so that whenever
samples are viewed the conditions are exactly the same.
Color Viewing booth / light box for color
matching.
It's difficult to see the true color under different light
sources in which measurement Color deviation intends
to occur when performing the color evaluation without a standard light
sources. To simulate different light sources to obtain an objective color, color
difference and color evaluation, we can put the test specimen into the color
viewing booth / color light box, so that it's easily to see the true color daytime,
night, indoor and outdoor, and ensure the color consistency.
The Problem of MetamerismMetamerism in textile shade matching is defined as a
phenomenon in which two colored objects appear same
in one light source but differ when the light source is
changed. This could be due to difference in pigments or
materials.
The spectral reflectance characteristics of the colors of
two objects are different , but the resulting tristimulus
values are same in under one light source but different in
another.

What is a color model?
Every colour has a colour space which can be pinpointed by coordinates given
by a computer. Colour can also be checked by eye and given a colour space,
but again this is open to subjectivity.
The three fundamental aspects of colour
are lightness, chroma and hue.
Lightness( bright colors,dark colors,light
colors, the lightness of color changes
vertically) is shown on the "L" axis. It indicates the
depth of a colour, ranging from white to black with grey in
between. One way of picturing depth of colour would be
to imagine a black and white photograph where every
colour is shown as a different depth of black, white or
grey. The lightness of the fabric sample would be
represented by a number on the "L" axis.
Chroma or saturation ( Vivid colors, dull colors, chroma changes
outward from the center) is shown as the distance
away from the "L" axis.
If the colour is described as being at the very outside
edge of chroma it will appear to the observer to be very
clean and bright. As it moves towards the grey central
"L" axis it will become greyer, flatter and more dirty.
Hue (Redder, greener, yellower, bluer etc.
hues form the color wheel) is the variation in
colour. For example, a blue may be very red - moving
towards purple lilac - and would appear in the blue colour
space at the red side. Different shades of blue would all
appear in the blue colour space but in different areas.
Lightness, chroma and hue are checked on all yarns and piece dyed fabrics to
ensure colour continuity standards are maintained to the highest levels. They
can be represented as a three dimensional figure.

Background knowledge of different light sources
CIE Fluorescent Illuminants
Artificial Daylight D65 which corresponds to a mid-day sun in Western Europe
/ Northern Europe is a commonly-used standard illuminant defined by the CIE.
It is part of the D series of illuminants that try to portray standard illumination
conditions at open-air in different parts of the world. Artificial Daylight D65 light
sources do not exist actually, only simulators. The quality of a simulator can be
assessed with the CIE Metamerism Index. —CIE S005/E-1998.
TL84 - CIE Fluorescent Illuminants, Light Source (F11), TL84 light sources
represent a tri-band fluorescent lamp. —CIE 1931.
CWF - CIE Fluorescent Illuminants, Light Source (F2), CIE F series light
sources represent various types of fluorescent lighting. CWF(Cool White
Fluorescent) light sources found in office environments.
Incandescent A - CIE Incandescent A is intended to represent typical,
domestic, tungsten-filament lighting. Its relative spectral power distribution is
that of a Planckian radiator at a temperature of approximately 2856 K. CIE
standard Incandescent A should be used in all applications of colorimetry
involving the use of incandescent lighting, unless there are specific reasons for
using a different illuminant. It is found in our home.
UV - UV Ultra Violet Black light to reveal the presence of fluorescent dyes and
bleaches.
U30/U35 - Neutral-white fluorescents have a CCT (Correlated color
temperature) of 3000K or 3500K.
