Required. Drawing color:

Hexadecimal value of RGB color. For example, specify the color white as "##FFFFFF" or "FFFFFF".
String value of color (for example, "black", "red", "green"). The default value of the drawing color is "black".
List of three numbers for (R,G,B) values. Each value must be in the range 0-255.

Usage

Use the ImageSetDrawingColor function to control the color of all subsequent drawing objects in ColdFusion images. For example, you can use this function to set the drawing color to red once, and then draw a circle, a square, and 10 lines in that color.If the color value is a string, specify a supported named color; see the list of valid HTML named colors in cfimage. For a hexadecimal value, use the form "##xxxxxx" or "xxxxxx", where x = 0-9 or A-F; use two number signs or none.

Example

<!--- Use the ImageNew function to create a ColdFusion image. --->
<cfset myImage=ImageNew("",200,300)>
<!--- Turn on antialiasing to improve image quality. --->
<cfset ImageSetAntialiasing(myImage)>
<!--- Set the drawing color to pink. --->
<cfset ImageSetDrawingColor(myImage,"pink")>
<!--- Draw a pink line. --->
<cfset ImageDrawLine(myImage,1,1,200,300)>
<!--- Draw a pink oval. --->
<cfset ImageDrawOval(myImage,40,50,80,40)>
<!--- Draw another pink oval. --->
<cfset ImageDrawOval(myImage,15,180,80,40)>
<!--- Draw a pink rectangle. --->
