Not that I expect any others to do the same, in the instance of my 2 witch elves, one is huge (st4) and one is small (st3) and is topless (armor deduction)

Sparky is right tho those examples arent solved by coloured bases. The fact that my opponent(s) can clearly see purple for my witch elves that most experienced bb players know have frenzy, can help them to remember to stay away from the sidelines.
If I could (for example) clearly see a skaven gutter runner, it would influence my positioning knowing that they got a high move and can make a run for it so spacing some tacklers back is to my advantage.
If I could clearly (for example) see mummies I can keep a 3 square minimum distance from them at a glance. Or blitzing what looks like a ghoul only to find out its actually a wight, could have influence my decision to take a wrestler on the blitz or not.
I tend to do a "meet the team" before each match anyway high lighting the positional differences if nothing else.
The worst or should I correctly say slowest game was against some orcs who had numbers on the back of their models. Every turn, what number is that
