You can use this online tool to generate code for a rollover effect that changes the color of text when the mouse rolls over it (on mouseover).
Try it out:Roll your mouse over this text.
Make your own: Fill in the form fields below then click on SHOW to display your code in the textbox at the bottom of the form. Click on RESET if you want to clear the form and start over. You need to specify the colors in 6-character hexadecimal code (the "hex code"). (You can use the Color Code Calculators to find the hexadecimal code for any of the Web-safe colors or use the Color Picker to choose a color from the Web-safe palette.)
