Hi!
When I see standings of some contest, I can see red submissions that failed on system tests or hacked, of course system test failed submissions are in bold font, but also hacked after lock submissions are in bold font. And in order to know whether it's hacked or failed on system tests I need to click the submissions or move the cursor to it. From first look we can't know exact verdict.
So, I suggest codeforces to change the color of submissions that got hacked. Ones which failed on system tests may remain unchanged or visa versa.
You can distinguish of course if you are not daltonic.
The hacked submissions are colored in dark red, and system test failed submissions in light red.
I think you knew it. It is known to everyone.
No, submissions failed on system tests are red with bold font and submissions that got hacked after lock are the same. Only hacked and not locked submissions are in normal font, but in red.
Check this:
A hacked after lock.
B failed on system tests.
Their color and font are same!
Well, Hmmm. Imagine that here was nobody. LOL ))
