`put-text-property'

In particular, you may want the :foreground attribute of the `face'
property.

E.g. try evaluating the following:

   (put-text-property (point) (mark) 'face '(:foreground "green"))

However, note that if the buffer's mode uses font-lock, font-lock will
_override_ any `face' property you set (to be its own); in a font-lock'd
buffer, you can use the `font-lock-face' property instead:

   (put-text-property (point) (mark) 'font-lock-face '(:foreground "green"))
