This logo was designed on the task request which was posted by @julienbh for the chrome extension of steemit called "Steemit is Fun" on @utopian-io.
Concept of Logo
The original logo of @steemit with a smiley icon is designed to make easy for users to understand about the plugin.
And regarding with colors, I have retained to original steemit colors, as to show that this plugin is child of steemit project.
These are the variable sizes for the logo.
