Is it possible????

Is it possible for me to adjust the rich text's color on the UI with my animation that managing the colour of it. So what am I going to do is to use an animation that make the Text UI fading in the end, but that UI Text is using rich text like " <color=red> my word </color> " so as long as I know the animation won't make any changes to my text's colour, because it is controlled by the rich text. So my question is, is it is possible for me to using the animation to manage the colour.
