Suppress warning profile

I believe you would need to turn the prompts off. You May be able to automate that in a script using  Scriptlistner code to save the current color setting, then turn the prompts off. Do the operation that may produce the prompt then restore the color settings. When you save and load Color setting they are stored in

"C:\Documents and Settings\User ID\Application Data\Adobe\Color\Settings\*.csf" on a Windows XP system locations vary with OS. You may want to generate a unique name to save the current setting and delete that file after reloading the settings. The name though will remain around as the current color settings in the color setting dialog. Also APP colorSettings string Read-write. The name of the current color settings, as selected with Edit > Color Settings.  from the Photoshop JavaScripting guide you may be able to play around with that string..... To get the current setting csf file set one with the prompts off then restore the original settings after the operation that may cause a prompt.. like

var saveColorsettings = app.colorSettings;

//alert("ColorSettings = " + app.colorSettings);

app.colorSettings = "JJMackProPhotoOff";

//alert("ColorSettings = " + app.colorSettings);

//operation

app.colorSettings = saveColorsettings;

//alert("ColorSettings = " + app.colorSettings);
