Appendix A
LUT Characteristics
The C
2
OS introduces a more advanced and precise approach to Color Control that includes selectable Color LUTs (Look Up Tables).
The Universal Color Space (UCS) is introduced and is the recommended color space LUT on the new c2OS console for colorimetric
accuracy. In addition, the c2OS can use a different LUT to reproduce Cineo2017 (the original color space used on the c80,
Standard410, LightBlades and LB800 products). In the future Cineo will be introducing more LUTs that will be used to map to other
color spaces and other fixtures. This document explains how Cineo c2OS Color and LUTs work with an explanation of the color
theory behind it.

UCS LUTs
UCS 2.0 LUTs are the preferred color space for the latest Cineo fixtures. It offers higher color precision, correlated to REC.2020 and
provides accurate linear dimming. Saturation control and Hue controls are more precise. Two UCS LUTs are offered in the initial
release on C
2
OS: UCS 27-65, with a CCT range of 2700K-6500K, and eUCS 20-100, with a range of 2000K to 10,000K.
Cineo 2017 LUT
Use when operating older Cineo fixtures with C
2
OS fixtures. This LUT matches the colors of the older S410, LB1000 and other Cineo
legacy fixtures.
