Use the color option to place your string onto your axes:

text(x, y, yourString, 'Color', 'r');

Color can also be a 3 number array for [r,g,b] with values in the range 0-1 to get any color you want. You can also change font size and font name with appropriate options,

When I said "View/Macros/Record Macro..." that is doing that from Microsoft Word. Just look at the tool ribbon in Word.

If you need to set the color inside the text document then you cannot do that: plain text does not have a color.

Changing the color of text can be done in some human-readable formats such as RTF; for example (thanks to pindari.com)

{\rtf1\ansi\deff0
{\colortbl;\red0\green0\blue0;\red255\green0\blue0;}
This line is the default color\line
\cf2
This line is red\line
\cf1
This line is the default color
}

You might be able to set color in Excel files, under some conditions.

If the goal is to write to the command window rather than to save to a file, then see File Exchange
