What does the apple and the colour represent in the avatar?

I’m new to lingq and I was wondering what the colour and the apple mean. I have a red apple in my avatar. Can anyone tell me more about it?

Welcome to the site! You can find out more about the apple here: Avatar Help

Thank you

If you reach Advanced 2 level in your target language, will you be considered a fluent speaker in the language? or Still a long way to go?

I think you’re usually B2 (upper intermediate) in the CEFR. Of course, it depends how much writing and speaking you’ve done while getting there.
