Make it clear what color means

Problem

I found it hard to know what color stands for in Rust Machine Learning Ecosystem section.

Can we clarify what each color means?

Prior art

In Are we web yet, we have following explicit label on each states.

• everything is awesome
• stable, tested and mature
• stuff's pretty great
• getting there
• stable but still maturing
• not yet stable, but progressing
• unstable/incomplete, needs work
• barely there, needs serious work
• basically nonexistent

Not revive an old-ish issue, but if you look at the about page on the website (link at the bottom of the page) it has the color key.

Then it's a discoverability issue. It'd better put a label on the main page.
