LSL: string osSetPenColour( string drawList, string colour )
C#: string osMovePen( string drawList, string colour )


Appends a PenColour drawing command to the string provided in drawList and returns the result.

This sets the pen's drawing color to either the specified named .NET color or to a 32-bit color value (formatted as eight hexadecimal digits in the format aarrggbb, representing the eight-bit alpha, red, green and blue channels).

For full opacity, use an alpha value of ff (e.g. ffff0000 for red); for varying degrees of transparency, reduce the alpha value (e.g. 800000ff for half-transparent blue).

The color names and hexadecimal color representations are not case-sensitive.

Example:

// Example of osSetPenColour
 
string hexDigits = "0123456789abcdef";
list colorNames  = [ "AliceBlue", "AntiqueWhite", "Aqua", "Aquamarine", "Azure", "Beige", "Bisque",
