I went to Outlook 2003 help on-line and followed the instructions which are as follows:
From the main Outlook window, on the Tools menu, click Options, and then click the Mail Format tab.
In the Compose in this message format list, click HTML.
Click Stationery Picker.
In the Stationery box, click the stationery you want to change, and then click Edit.
Select the options you want to use.
Note This procedure is available only if you use HTML as your message
But nothing has changed when I open up this message,same colors appear.
