ugly-siding

At a previous job, a threat I made for doing software development badly was to repaint your siding an ugly color. What color would be the worst?

• Puke green~
• The worst shade of yellow you can think of~
• Pepto-bismol pink~
• Acid green~
• Bright red and bright green splattered about with no discernable pattern~
• Black and magenta checkerboard~
