In SCADA systems color can be used to indicate:
The rest of this page describes how colors are configured in Fernhill SCADA.
In Fernhill SCADA you can configure a color using:
A color keyword is an identifier that corresponds to a color value. For example:
For the complete list of supported keywords, see Named Color Values.
An RGB color value sets the red, green and blue components of the color separately. For example:
Example | Description |
---|---|
#f00 | Three digit hexadecimal. |
#ff0000 | Six digit hexadecimal. |
rgb( 255, 0, 0 ) | Function notation using decimal values. |
rgb( 100%, 0, 0 ) | Function notation using a percentage to set a color component. |
Note: These are different ways to define the color red.
Hexadecimal notation is the '#' character followed by three or six hexadecimal characters. The two notations are called three-digit and six-digit respectively. For example:
The three-digit notation is expanded to the six-digit notation by copying digits. For example, #08f expands to #0088ff. This ensures that white (#fff) can be represented in three-digit notation accurately.
Function notation uses the function name "rgb" and three parameters to set the red, green and blue components of the color.
A HSL Color Value is defined using three parameters:
Parameter | Description |
---|---|
Hue | An angle on the color circle, measured in degrees. 0 corresponds to red, 120 corresponds to green and 240 corresponds to blue. |
Saturation | The percentage saturation of the color. 100% is fully saturated. 0% is a shade of gray. |
Lightness | The lightness of the color. 100% is white. 0% is black. |
