Two ways to color text in org-mode come into my mind:
1.) Simply add the usual LaTeX code
@@latex:{\color{green}@@This@@latex:}@@ is green.
2.) Use John Kitchin's org-colored-text.el
After downloading the file to your load-path
directory, put the following in your init.el, which lets you use org-links to color text:
(require 'org-colored-text)
;; Taken and adapted from org-colored-text
(org-add-link-type
"color"
(lambda (path)
"No follow action.")
(lambda (color description backend)
(cond
((eq backend 'latex) ; added by TL
(format "{\\color{%s}%s}" color description)) ; added by TL
((eq backend 'html)
(let ((rgb (assoc color color-name-rgb-alist))
r g b)
(if rgb
(progn
(setq r (* 255 (/ (nth 1 rgb) 65535.0))
g (* 255 (/ (nth 2 rgb) 65535.0))
b (* 255 (/ (nth 3 rgb) 65535.0)))
(format "<span style=\"color: rgb(%s,%s,%s)\">%s</span>"
(truncate r) (truncate g) (truncate b)
(or description color)))
(format "No Color RGB for %s" color)))))))
Then use color
links like this:
[[color:green][This]] is green.
