Using the Color Picker
.
The button {Color Format} is for toggling between native (RGB, CMY, color scroller, or color select)
and hue and saturation. {Gel} is for opening up manufacturer catalogs of gels. To display a specific
manufacturer’s catalog, press the specific manufacturer or catalog and select the desired gel. The
{Bright. to Full} button will only appear if selected channels have a brightness parameter.
When channels are selected and a specific gel is chosen, the color picker will show a dot which
represents the selected fixture(s). The dot is a visual indication of the color each fixture can
accommodate, closest to the gel selected. This tool is most useful when color matching between
different fixture types to maintain an even field of color. You can click in the picker to go to the hue
and saturation values or you can match a specific gel color from the manufacturers’ list on the right.
Selecting a specific gel will also produce the hue and saturation value.
.
Gel colors can also be manually entered into the command line. [6] {Color} [1] [/] [1050] [Enter]
assigns Apollo gel number 1050 to channel 6. Each of the manufacturers have been assigned a
number, which can be seen beside their name in the Color Picker display.
When channels are selected, a black line may appear in the color picker. This line indicates what
colors can be mixed by the fixture. If a color lies outside of the line, that color is out of the range of
that device. When setting a color outside of the black line, the fixture will get as close as possible to
the desired color. If no black line is visible, the fixture has not yet been calibrated and the color
matching will be approximated.
The gel picker is normalized to 3200 degrees. Therefore, if you are setting Rosco 80 (R80) on a arc
source device, it will appear to be the same color as R80 on an incandescent source.
Color Control
Depending upon the specific device, color can be established manually with the encoders using:
• CMY color-mixing
• Hue and saturation color mixing
N o t e : When using the color and gel pickers for 'non-standard' LED fixtures, such as
those that use RGBA, RGBW, and RGBAW, the Amber output will live halfway
between red and green. White output will not be driven by hue/saturation directly.
Hue is the actual color. It is measured in angular degrees around the cone
starting and ending at red = 0 or 360 (so yellow = 60, green = 120, etc.).
Saturation is the purity of the color, measured in percent from the center of
the cone (0) to the surface (100). At 0% saturation, hue is meaningless.
Brightness is measured in percent from black (0) to white (100). At 0%
brightness, both hue and saturation are meaningless.
