Color Keyword

You can use these color keywords in Fernhill SCADA:

RGB Value

An RGB Value is the '#' character followed by three or six hexadecimal characters. The two notations are called three-digit and six-digit respectively. For example:

• Red in three-digit notation is: #f00.
• Red in six-digit notation is: #ff0000.

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.
