Ozeki SMS Wall makes it possible to change the colour and the size of the scrolling text. To perform the changes, you need to edit the C:\Program Files\Ozeki\Ozeki SMS\SmsWALL\index.html file with a text editor, such as notepad.

To change the colour of the scrolling text,  find the line starting with the word iPhoneFront in the HTML file. In this line you can modify the display attributes of the sender phone number. Right under this line there is a line starting with the word iMessageFront. Here you can set the display properties of the incoming SMS messages. 

To specify the text colour,  change the hexadecimal RGB value after the text colour. The text size can be modified by changing the value of the font-size attribute (Figure 1). You must create a standard html prefix and postfix for the phone number and the message text. Make sure not to use apostrophes in your HTML code. 

If you use a vivid text colour with a complementary background colour the result can be nice. You can also add custom HTML code to this HTML file to gain a more appropriate display.
