You can change the color using a style sheet, but its display will depend on whether the user's browser supports CSS. Here is how you would do using an inline style sheet.
First define the style in the HEAD of your document.
<STYLE>
.t4 {font-family: "courier new"; color: 003300;}
</STYLE>
Then, call the style on your text box:
<INPUT CLASS="t4" TYPE="text" NAME="f" VALUE="Some Value">
Hope this helps.
