Color (DDF-Syntax) DMXC3 | Article describes DMXControl 3.2.3 |
|
RGB, HSV, CMY, and Colorwheel, as well as Colortemp, are functions in the DDFs for DMXControl 3 to control the color according to the used color mixing system. All the aforementioned functions are assigned to the group Color. The GUI generates an independent control panel for controlling, regardless of the color mixing system, and allows for direct selection of fixed colors.
Contents
Color
A luminaire can generate a color in two ways. For each color mixing system, there are technically different mixing systems, which are assigned in DMXControl 3 as follows:
- additive color mixing:
rgb
,hsv
- subtractive color mixing:
cmy
,colorwheel
RGBx color mixing
RGB color mixing is one of the additive color mixtures. Different colors are added during color mixing to achieve the desired mixed color. Therefore, the colors red, green, and blue must each be set to maximum brightness to obtain the color white. DMXControl 3 currently supports the standard channel colors, which are listed in the table below. Both the spelled-out node names and the abbreviations in XML can be used:
DMXControl 3 calculates colors in the range of 0 to 1 , not in the range of 0% to 100% or analogously to DMX in the range of 0 to 255 . Therefore, the device control defaults to showing the values 1; 1; 1 for white or 0; 0; 0 for black. So if you need to "clip" the value range to the DMX channels for the colors in a DDF, note the value range from 0 to 1 .

Operation of additional LED colors
All additional LED colors such as white, amber, UV, etc., which are installed in the device alongside the RGB LEDs, are not initially controlled after adding the device to a project. In the device properties, accessible, for example, via the Stage View, the behavior for each device can be adjusted individually under the entry White Automix Mode:
- None: No control of the white LED (default setting)
- Add white: All four LEDs at 100% for the color white
- Only white: Only white LEDs at 100% for the color white
Operating ranges for additional LED colors
In DMXControl, the operating ranges for the additional LED colors are predefined in the program but can be adjusted by the user in the respective DDFs. The operating range indicates when the HAL begins to include the color amber, indigo, etc., in the color mixing. These specifications are defined separately for each color using the following four attributes. All four attributes together form a trapezoid in the color spectrum, provided the left and right maximums coincide at a point. In the latter case, a triangle is formed.
hueLeftBottom
: Left zero point of the trapezoidhueLeftTop
: Left maximum of the trapezoidhueRightTop
: Right maximum of the trapezoidhueRightBottom
: Right zero point of the trapezoid
The default values are noted in the table below. The values of the attributes are given in degrees.
Color | hueLeftBottom | hueLeftTop | hueRightTop | hueRightBottom |

<amber dmxchannel="4" hueLeftBottom="0" hueLeftTop="60" hueRightTop="60" hueRightBottom="120" />
</rgb>
CMY color mixing
CMY color mixing is a so-called subtractive color mixing method. Starting from the color white, various color components are subtracted using three disks in the colors cyan, magenta, and yellow to achieve the desired mixed color. The disks are transparent on one side and fully colored on the opposite side.

Color wheel
A color wheel consists of several translucent elements arranged in a circle, colored in different hues. This gives the light beam of a moving head or a scanner "its" color. Depending on the design, half colors are also possible, where the color wheel is always positioned exactly in the middle between two adjacent colors in the light beam.
The number of colors for a color wheel is effectively unlimited. However, due to technical limitations, only 255 different colors plus white are possible. A DMX channel can only accept values between 0 and 255.
The following variants are not supported by the DDFCreator and must be manually edited after insertion:
|
The so-called split colors, that is, the simultaneous display of two colors directly adjacent on the color wheel, are not yet natively supported by DMXControl 3. |
Basic functions
There are two ways to define color in the DDF:
- Custom Definition: You work in the
val
attribute with the hexadecimal code of the corresponding color and name the color in thecaption
attribute with an individual "clear name". The Control window for the color (Color Control) and the Device control (Device Control) also display this name. - Definition using color list: There are two subordinate variants.
- Calibrated colors: You use the color lists stored in DMXControl 3 according to Lee, Chromagel, or Supergel, which always lead to the same color output for correspondingly calibrated devices. To do this, you only enter the three-digit number of the color as the value of the
val
attribute together with a prefix letter as an abbreviation for the color list to be referenced. DMXControl automatically takes over the corresponding name in the Control window for the color and in the Device control. See also the table below for details. - White tones: To retrieve color macros or presets for white tones stored in the device, you only enter the corresponding color temperature including unit as the value of the
val
attribute, such as3750K
. Based on this input, DMXControl 3 automatically generates the color-graded buttons in the Control window for the color and in the Device control, and also displays the value of the color temperature in plain text.
In all cases, the buttons with the colors then automatically appear in the Control window for the color and in the Device control.

Chromagel | C |

Supergel | S |
It is permissible to enter the same values for the mindmx
and maxdmx
attributes. This is always necessary when the color wheel does not have a fixed position for a specific color and can be positioned arbitrarily.

On the internet, there are several converters under the search term "RGB to HEX" with which you can convert RGB colors to the HEX format or generate the HEX value directly via a color wheel.

Color temperature
Color temperature indicates how warm or cool a color should be displayed. Classic PAR spotlights produce a warm white with a color temperature of around 2,700 K. Discharge lamps in moving heads or scanners, on the other hand, have a color temperature between 7,000 K and 8,000 K, resulting in a perceived cold light.
Technically, color temperature is achieved through a filter that is applied in addition to the current color output. This is done either mechanically in the form of a filter disc that is inserted into the light beam. This solution is usually found in all devices that have a white light source such as a discharge lamp or a white LED and produce color mixing subtractively. In devices with additive color mixing, such as RGB, RGBW, RGBWA spotlights, etc., color temperature can also be adjusted electronically. In both cases, however, it is possible to change the color further. The change in color temperature becomes increasingly important the closer the color gets to white, i.e., the center of the color circle.
The following variants are not supported by the DDFCreator and must be edited manually after insertion:
|
The "Color Temperature" function should not be used if white tones are stored in the form of color macros in a device, allowing only either color mixing via the color wheel or the selection of a preset white tone. |
Case | Code example |
---|---|
Separate DMX channel for color temperature | <colortemp dmxchannel="0" >
<range minval="3200" maxval="7000" mindmx="0" maxdmx="255" />
</colortemp>
Color temperature on DMX channel 1:
|
Color temperature active only over a part of a DMX channel | <colortemp dmxchannel="0" >
<step type="off" mindmx="0" maxdmx="5" />
<range minval="3200" maxval="7000" mindmx="255" maxdmx="6"/>
</colortemp>
Color temperature on DMX channel 1:
|
Color temperature with its own standard value | <colortemp dmxchannel="0" defaultval="5575" >
<range minval="3200" maxval="7000" mindmx="0" maxdmx="255" />
</colortemp>
In addition to the previous example, the color temperature is set by default to the custom value of 5,575 K using the additional attribute |
Virtual color temperature by mixing different LED colors | <colortemp>
<amber dmxchannel="0" temp="2400K" />
<warmwhite dmxchannel="1" temp="3600K" />
<coldwhite dmxchannel="2" temp="7000K" />
</colortemp>
Virtual color temperature generated by an automatic mixing ratio of LED colors amber, warm white, and cold white in the range of 2,400 K to 7,000 K with a temperature value deviating from the standard value for the available LED color temperatures.
