Cyan, Magenta, and Yellow
These parameters determine how the individual color mixing wheels move. Channel
18 controls Cyan, Channel 19 controls Magenta and Channel 20 controls Yellow.
The Color Function value choosen determines the available color wheel settings, (see
Table 4-7).
CTO and CTB
Color Temperature Orange (CTO) and Color Temperature Blue (CTB) wheels allow a
full range of color temperature adjustment in x.Spot fixtures. Channel 21 and 22
control the CTO and the CTB wheels respectively. Each wheel can be set from Full
filtering to Open (no filtering). Full CTO adjusts temperature to a low value of 3,000K.
Full CTB brings the color temperature to a high of 7,500K.
Both CTO and CTB contain a diffusion filter wedge used to adjust beam flatness.
Beam flattening equalizes the intensity across the beam to minimize “hotspots”.
CTO and CTB are not affected by Color Mix function settings.
Table 4-6 Color Mix Function Descriptions
Color Function Description
Pure Mix
Allows color wheel movement from open (white) to saturated color (permits a
smaller “step” between color wheel positions for color crossfades).
Continuous Allows complete 360 degree color wheel movement.
Spin
Puts all three (cyan, magenta, and yellow) color wheels in spin mode. Wheel
Spin speed, direction, or fixed position can be set individually on CMY channels.
Cycle
Uses only the color-mixing portion of the cyan, magenta, and yellow color wheels
to cycle colors from red to green to blue at variable speeds (rate set by cyan
DMX channel).
Random
Performs a pseudo-random color chase of 12 factory-selected colors using the
cyan, magenta, and yellow color wheels at variable speeds (rate set by cyan
DMX channel).
Blink
Defined using Continuous wheel operation. Shutter snaps closed during any
color move, then re-opens.

Description
Pure Mix Mode Allows exact positioning of the color wheel from full color to white.
Continuous Mode
Allows exact positioning of the color wheel from white to full color to
white over the full revolution of the wheel.
Spin Mode Determines the color wheel spin speed, direction, or fixed position.
Cycle & Random Mode
Determines the speed at which all three (cyan, magenta, and yellow)
color wheels move to the next cycle color or random color. The Cyan
color wheel sets the rate for all the wheels.
