In the PROMOTIC system it is better to use the Pm.ColorRgb method.
n = RGB(red, green, blue)
|red||(Integer) Number between 0-255. Red component of the color.|
|green||(Integer) Number between 0-255. Green component of the color.|
|blue||(Integer) Number between 0-255. Blue component of the color.|
Application methods and properties that accept a color specification expect that specification to be a number representing an RGB color value. An RGB color value specifies the relative intensity of red, green, and blue to cause a specific color to be displayed.
The low-order byte contains the value for red, the middle byte contains the value for green, and the high-order byte contains the value for blue.
The value for any argument to RGB that exceeds 255 is assumed to be 255.
nRGB = CLng(blue + (green * 256) + (red * 65536))
