Using the Color Picker

The Color Picker is a window that can be used to select a color in fixtures with a mix color system.

It does not affect color wheels, only color mixing systems.

The color picker provides convenient access to mixing the desired color using several color mixing and selection options. The method used is independent of the fixture's actual color mix system (LED emitters or color subtraction).

Open the Color Picker

The color picker is created like any other window; see Add windows. It is found in the Common tab.

RGB and HSB color space:

Tap RGB/HSB Space in the title bar of the color picker to switch the color picker's color space. There are four options:

Fixture Type: The color space is defined by the emitters of the respective fixture type.

Standard: Plasa Standard E1.54 for Color Communication in Entertainment Lighting.

Rec.2020: ITU-R BT.2020 or Rec. 2020, is an audiovisual industry standard for ultra high definition (UHDTV).

Rec.709: ITU-R BT 709 or Rec. 709 is an audiovisual industry standard for high definition (HDTV).

The mode can be selected using the buttons in the title bar. This is a short description of the different modes.

CIE: A CIE color space area picker with Brightness, Quality, x, and y on-screen faders.

Color Picker: An HSB area with Brightness and Quality on-screen faders.

Fader: On-screen faders to adjust RGB, CMY, HSB, Brightness, and Quality.

Book: This is a swatch book with colors from different filter manufacturers.

Quality

The Q fader or quality fader is available when the fixtures have a color mix system of more than three colors. It controls how the colors are mixed.
Q at 100 results in kind of small band mixing (the specialized emitters are used). 0% results in a broad band mix. That uses as much emitters as possible to mix the color.

CIE

The CIE (Commission Internationale de l’éclairage) standard uses a figure that indicates the visible light spectrum. 

The non-shaded part of the figure (the RGB triangle) shows the colors that the specific fixture can mix. Tap inside this area to select a color.

If the fixture has more than 3 mixing colors, the shaded part will become smaller.

The color picker offers the possibility to be used in Constant Brightness Mode. The Constant Brightness mode can be enabled by tapping Constant Brightness in the title bar. The default setting is off.

If the constant brightness is disabled, the selected color is mixed with maximum brightness when the brightness fader is set to 100%. In this case, the fixture's output intensity is not kept constant but changes with the color. If the constant brightness mode is enabled, the maximum overall brightness is limited to the brightness of the fixture's darkest emitter. Changing the color in constant brightness mode does not change the output intensity of the fixture. 

Except for the Fixture Type color space, the gamut of the selected color space is displayed in the CIE color picker with a white line. The shaded area only depends on the emitters of the fixture. It does not change with the Color Space (only the small white triangle changes with the selected color space). Color mixing in the RGB tab and the HSB Color Picker depends on the color coordinates of the RGB primaries of the selected color space.

The CIE Color Picker displays the spectral profile (or curve) at a specific temperature that corresponds to a specific peak wavelength, and vice versa. As the temperature of the black body increases, the peak wavelength decreases (Wien's Law). The intensity (or flux) at all wavelengths increases as the temperature of the blackbody increases. That is what we call the black body curve.

Color Picker

 Tap the HSB field symbol in the title bar, also known as a Color Picker, to adjust the color mix.

Here it is possible to tap a color in the HSB field. The x-axis (left/right) is the Hue value. The y-axis (up/down) is the Saturation value, and the B-fader on the right side is Brightness.

Fader

On-screen RGB, CMY, HSB, Brightness, and Quality faders.

Here it is possible to adjust the colors using RGB, CMY, or HSB. The Three-color systems are interlinked. This means that adjusting the colors in RGB also moves the CMY and HSB faders.

Book

The swatch book is a library of filter colors from different manufacturers. This can also be accessed using the Gel keyword.

The manufacturers are listed on the left side, and the right side displays the manufacturer's colors.

There are three new fields displayed at the top of the window (below the title bar).

• Filter is to enter a name or a key of the color to limit the list of colors.
• View defines how the color list is displayed. It is a swipe button with the following options:
  • Big Icons - This displays a big color example. Below the color are the name and color key.
  • List - This displays a list with Name, Key, and Color columns.
  • Small Icons - displays a small color field only.
• Sort has three different ways to sort the displayed colors. It has the following options:
  • None - the list is not sorted and is displayed in the order in the library.
  • Key - Sorted by the color key number.
  • Name - The colors are sorted by the color name.

The manufacturer list includes many of the filter manufacturers. It also includes MA Lighting, even though MA does not produce color filters. The MA Lighting library contains all the primary colors and the most used colors.
