As someone who is colour blind, the distinction between the different types of connection isn't clear, would fail an accessibility test, and isn't readily understandable. Editor should provide different pin styles to show different input types.
Not sure we need to do different pins. We have link highlighting to show invalid connection. This is an enhancement if ever do. Marking it enhancement.
This is an accessbility bug.
We show a cross on operators when do a link to show which operators can not be connected. This is good enough, so that one with color blindness can see where a connection can not be made. I am closing this bug. QA please verify if this is still an A11Y bug.
I need more information from bing to understand the issue.
Verified as not fixed.
