Not sure if it's possible on the app. The only way to change the color of your text is by using the "Enhanced Editor" ... I am using the IPad 2 and apparently it's not compatible with the site's EE. Try using the full version on a non iOS device, and you might be able to utilize the EE. Otherwise you'd have to know/memorize the BB Codes. i.e [color ______ ] text------ [/color_____ ] Each color has a designated number code...which you would enter into the blank spots between the brackets.
