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 green3
• The worst shade of yellow you can think of3
• Pepto-bismol pink2
• Acid green
• Bright red and bright green splattered about with no discernable pattern5
• Black and magenta checkerboard2
