Jeff when you first open the file up in Photoshop..........make sure you are working in RGB Mode before making any changes to the file.Once you complete your changes CNANGE the file to INDEX colour Mode and then SAVE the file as TIFF format, this should then be correct.Hope this helpsJohnDC10 ProjectB737-500
