Collection Window
The collection is the heart of SpectraShop. A collection is equivalent to a
folder which contains the specimen information, including the spectral data.
Multiple collections may be open simultaneously.
Specimens may be copied or dragged to the tool windows for various
analyses.
Measurements are automatically sent to the active collection.
Important Note: Remember that some collections of colors may be subject
to copyright restrictions, so please check your legal rights and restrictions
before publishing or distributing your collections to others.

Graph 2D Tool
Create graphs of colorimetric properties.
Begin by pasting, or drag and dropping, a group of specimens
from any collection into the Group list.
Groups
Paste or drop specimens here to create
a display group.
Each paste or drop will create one
group.
Group Specimens
Check or uncheck the boxes to
display or hide the groups or individual
specimens.
Groups cannot be added to later.
Click on a group’s name to edit it.

Lighting Tool
Paste, or drag and drop, emissive-light specimens into the Test Light
Sources list to calculate CRI and CQS.
CRI Calculation Method
CIE 13: Reference spectrum is based on the
CCT of the test specimen; a Plankian radiator
below 5000 K, or a D illuminant above 5000 K.
ISO 3664: Reference spectrum is always D50.
Custom CQS Test Patches
Put reflective specimens here to
calculate their color differences
under the currently selected
test illuminant compared to the
D65 illuminant used as the CQS
reference.

Calculate Tool
Paste, or drag and drop, specimens into each list,
then select to operation to be performed on the
list, or between adjacent lists.
Each list will appear once the previous operation
is selected.
The calculations are performed from left to right
with the final results placed into the currently active collection.
Calculations are performed on a single list for
the average, normalize and scale by operations,
between two lists for the add, subtract, multiply,
divide, and average by rows operations.
Step 1. Enter Specimens in List 1 (required)
Step 3. Enter Specimens in List 2, 3 or 4 (optional)
Step 2. Select Operation for List 1 (required)
Step 4. Click Calculate (required)
After all the desired lists have specimens
entered and the appropriate calculations
selected, the calculated results will be
appended to the specimen list in the currently
active collection.

Difference Tool, Compare Many to a One
When a single specimen is used for the reference, each test
specimen is compared against the reference.
This method is useful for quality testing. Routing
measurements directly to the test list allows for monitoring
quality as a test proceeds.

Difference Tool, Compare One List to Another
With more than one reference specimen, each test specimen is
compared against the reference in the same row. This is called a
paired comparison. This type of test is useful for comparing one set
of specimens against another, such as one test chart against a set of
reference values.

Chart Difference Tool
When the Show Chart button is clicked in the Difference Tool
window, the Chart Difference Tool window appears. Select a
chart definition file prepared with the Chart Editor to specify
the chart’s layout.
Once the chart has been specified it will be drawn in a colorcoded format. Each patches name and its difference from
the reference value are displayed. The color of each patch
corresponds to a difference range specified by the Difference
Zones controls.
Step 1. Select a chart definition file (required)
Step 2. Set each zone’s difference range (optional)

Search Tool
This tool will search through any, or all, of the currently opened
collections for specimens whose spectra match those in the For
matches to list.
Select each test specimen and result specimen to compare their
spectra graphically and their colors.
This tool can allow for searching through measurements of color
collections for matches to your test specimens.
Important Note: Remember that some collections of colors
may be subject to copyright restrictions, so please check your
legal rights and restrictions before publishing or distributing your
collections or matches to others.
Set Search Parameters
Step 3. Click on each test specimen
Any matches found are listed in the
Results list as each test specimen is
selected.
Step 1. Place test specimens here
Step 2. Click to perform the search

Light Source Tool
This tool will create a Plankian or D-series light source specimen
and enter it into the current collection.
