I want to know everyone’s favorite color…by their wavelength. If you need help, here you go:
My personal favorite is right around 400 nm. And it’s entirely for aesthetic reasons.
So what is yours and why?
(Yeah, I know…everyone is going to pick some non-optical frequency. And yes, you have to stick to photons. Maybe we can do sonic waves another week…)
50 shades of graphite November 1, 2012

This seems like an odd thing to ponder, but it makes sense to my currently sleep-deprived brain: does anyone know how people tend to react to ink color? I know a lot of my students get upset when they see red ink. I tend to use gel pens, however, and use a lot of pink and orange in particular for grading. The funny thing is, they almost seem to think this is neat or cute. (This is somewhat surprising as most of my students are male: I would’ve expected them to roll their eyes at me for being stereotypically female because I use a pink pen…) Lime green is another popular color.
Honestly, though, it seems like they react far more positively if I stay away from using the dreaded red pen. They’re also more likely to read my feedback. Last year, they requested me to use pink in particular when one student chuckled about his comments being written in that color. I told them there were other possibilities, too. No, they wanted pink.
Has anyone else observed this?
And yes, I’m aware the graphite is used in pencils and not pens. I just couldn’t come up with a more catchy title.
I also blog at Engineer Blogs, home away from home to some of the best engineering blogs.
