I'd argue the weather icons are difficult to "distinguish" at any size. i.e. they don't really mean much to me - they are encoded with information that I interpret in a binary fashion - reliably passing - somewhat broken in the past
On the front page I have icons as below. I have no idea what they mean apart from the sun probably meaning the build is ok and has been for a while. Also - in classic - the icons are hoverable with build status information - in BlueOcean they have no additional feedback.
Icons
What is the sorted order? Sunny, clouds, clouds with rain, clouds with lightning? Is that good for usability / discoverability?
Hover information
Have I derailed this ticket sufficiently now?
Low priority but we could sort this one out quickly
