6: Taking Measurements
3. Set
Measurement Type to the desired setting (Reflective or Emissive).
4. Set
Observer to the desired setting (2 degree CIE (1931) or 10 degree (CIE 1964)) to determine
which color matching function will be used. See the examples below.
CIE color matching functions for 2 degrees (CIE 1931) (left) and 10 degrees (CIE 1964) (right)
5. If you chose Reflective color measurements in Step 3, specify the following settings:
a. Illuminant – This is a theoretical, CIE-defined illuminant. It has nothing to do with the actual
lamp being used in the measurement.
b. Reference
Tile – Normally set to White if you are storing the reference spectrum using a
perfect reflector.
6. Activate the color measurements that you are interested in on the right side of the screen.
7. Click OK.
