How do you use bold and colored text

Bold text is [bb][/bb] (only with one b I used two so you could see it) and you put those brackets around a word or group of word to get Bold. To get colored text depending on whether you are on mobile or not (how easy seeing this is/typing) the colored button is two captial A's the left one white and the red one red. If you highlight what you want to color then click the button you get to select the color hex. For example. I hope this helps.
