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.
