Finding an equivalent or a cross-reference to a given color can be a daunting
task. To facilitate this task we offer to find / calculate / derive / deduce
such colors for you. The available conversions are shown in the following table:
| BS 5252 |
| FED-STD-595B |
| Munsell |
| Pantone |
| RAL CLASSIC |
| RAL DESIGN |
| XYZ / L*a*b*/ etc. |

- BS 5252 comprises the colors
referred to by BS 4800, BS 4900, BS 4901, BS 4902, BS 4903, BS 4904, and BS
6770. Due to the very limited number of
colors in this British Standard, it is unlikely that a perfect match will
occur. The nearest chip(s) will be given with a color difference value.
- FED-STD-595B comprises 611 color
chips. Because of this limited number of colors, it is unlikely that a
perfect match will occur. The nearest chip(s) will be given with a color
- Munsell Hue Value/Chroma values with a one
decimal place precision will be given (ex.: 4.5RP 5.7/11.4).
- Conversions to Pantone Coated, Uncoated and
offered. If unspecified, a Pantone Coated match will be given.
- RAL CLASSIC comprises 210 color chips. Because
of this very limited number of colors, it is unlikely that a perfect
match will occur. The nearest chip(s) will be given with a color difference
value. Semi-gloss chips are assumed.
- The nearest RAL DESIGN chip(s) as well as the
exact value in RAL DESIGN notation will be given.
- A chip color can be given using any
standard CIE notation, for any standard Illuminant and for the 2 or 10
degree Observers (CIE1931 or CIE 1964).
TRANSLATION / CONVERSION TYPE
| Price |
| F1 || First conversion FROM a color system || 30.00 US$ |
| F2 || Second, and other, conversion(s)
FROM a color system || 25.00 US$ |
| T2 || Obtaining conversion data TO a
second, or more, destination color system(s) || 20.00 US$ / each |
- Example 1: One color conversion, from FED-STD-595B to RAL
The cost of this conversion, item "F1", would be 30$.
- Example 2a: Two color conversions, both FROM RAL CLASSIC
The first conversion would be 30$ ("F1") and the second 25$ ("F2"),
for a total of 55$.
- Example 2b: Two color conversions, the first from Pantone
to Munsell, and the second from RAL CLASSIC to Munsell. The first conversion would be
30$ ("F1"); the second, from a different color system,
would also be 30$ ("F1"), for a total of 60$.
- Example 3: Two sets of color conversions, both from Pantone,
to Munsell and to RAL DESIGN (i.e. four conversions). The first conversion
set would be 30$ + 20$ ("F1" + "T2"), and the second
set would be
25$ + 20$ ("F2" + "T2"), for a total of 95$.

- We will not provide translation services for
metallic, pearlescent, or fluorescent colors, or any color which has a hue
which varies with angle or temperature.
- Although we can provide equivalents to basically
any color which can be measured in reflectance, you should be aware
that many factors affect color perception, among them:
metamerism: a colored sample can be perceived of being of different
colors when viewed under various lighting conditions. The effect varies
according to the pigments or dyes used for coloring, and with the spectrum of the
illumination. For instance, paint and ink samples of the same color under a
halogen lamp may look different under sunlight. A color match which takes
into account this effect requires samples colored or dyed with the same
processes and materials as the ones used (or planned to be used) in the
finished products. For example, you cannot predict the metamerism of a wall
paint using a Pantone color chip made from ink. Such a study is not included
in the translation services quoted above but can be quoted separately.
gloss: Many applications require specific gloss properties. This
property is often described in three "generic" levels such as: matte,
semi-gloss, and gloss finish. More precise gloss requirements can be defined
and measured with gloss-meters, which are specifically designed for this
- As a result of manufacturing tolerances, color
patches of the same color are not absolutely identical. Even when
manufacturers offer colorimetric reference numbers, these values will not
exactly match the sold samples. In addition, color chips are often offered
in various qualities, sometimes up to three levels, with a correspondingly
higher cost for the best ones. Some suppliers give tolerances for these
quality levels, and others don't. On top of that, most colors samples will
fade with time, and with exposure to light and air contaminants. For our
translation services, we use either reference data from manufacturers, or
high quality samples measured with calibrated equipment. Please include in
your requirements any specific goal for maximum acceptable color difference.
- Because of the perception effects described in
point 2 and the tolerances of physical samples mentioned in point 3, we
strongly suggest to our customers to buy samples of the identified
cross-references for final assessment and quality control. We can provide
suppliers names on demand. You can also send us a sample of the end product
to be compared against your requirements; a quote based on an hourly rate
would likely be sent for such an analysis.
