When you send me a document with bright yellow highlighting on it, here's what happens:

1. I open the document.
2. My eyes register the yellow as Bright Flashing Lights of Doom.
3. My brain, sensing a migraine, goes into panic mode.
4. I close the document and walk away.
5. Your document is wiped from my memory.
6. Our deliverable is late and you send me nastygrams, typically covered in Bright Yellow Highlighting.
7. Repeat.

Please don't use #BrightYellow highlighting.
