You have to write a code that consists of 5 separate parts to choose a colour. First, colour. Second, saturation. Third, brightness. Fourth, transparency. Fifth, size. If I wanted a totally black colour, I'd write 000/000/000/000/005. Red will be 100/100/100/000/005. White will be 100/100/100/000/005. And orange will be 010/100/100/000/005. All of them are on a scale of 000 to 100. Click the 'next backdrop' sign to change the backdrop. There are 32 preset colours: red red orange orange orange yellow yellow yellow green green green blue blue blue purple purple purple red teal black brown white cyan magenta gray gold lime rose tan banana coral maroon turquoise cerulean blue honeysuckle emerald green buff pink There is also a HEX code option, but you must include the hashtag.
