How to style points in QGIS based on multiple attributes

[المشرف العام]

While trying to find a useful way having earthquakes displayed, I noticed that it isn't that easy to manage.

I'd like to be able to recognize the "Magnitude", "Date", and "Depth" from the style of the point. Something like:

• size: based on magnitude
• depth: basic color (ex. 30 blue)
• date: intensity of color as shading from 100% color to white/...

Is there a way to do so without defining dozens of rules?
