It all started with a stupid drawing meme were you send an artist three emojis and they make a oc out of it.
Their kind of fairies take care of flowers and stuff, painting them when spring comes around and in general take care of the stuff around them.
Not all of them are born to do the job so of course there are a few among them that work other stuff. Those born for it mostly have a color on them they then use for the flowers ‘n stuff. Often two of them have to mix their colors to get a new one.
They also known to kill humans who hurt nature without a good reason and use their soul to replace what they have destroyed. Some of them also smoke flower pollen (?) which is like weed for them because some of them are super stressed sometimes, these two for example.
