>Yep, you are right. Works with jpg but not with gif or png.

It may have to do with the color pallete of the gif you are using.  For example 
if you run the following code, the text appears red on the Google logo. 
Presumably because the logo's color palette contains red, or a very similar 
color.  The text on the other images appears gold.  I believe that is caused by 
dithering, which will approximate the closest match to "red" in the image's 
color palette. With the last two images, the closest match seems to be a gold 
color.

<cfset testDrawingColor("Google Logo", 
"http://www.google.com/intl/en_ALL/images/logo.gif";)>
<cfset testDrawingColor("HouseOfFusion logo", 
"http://www.houseoffusion.com/_/hof120.gif";)>
<cfset testDrawingColor("HouseOfFusion Banner", 
"http://www.houseoffusion.com/images/nav/houseOFfusion.gif";)>

        <cfset imageSetDrawingColor (testImage, "red") />
