You're right. Light with lots of blue in it, like the dawn, wakes us up.

Want to hear a dumb story? Been patting myself on the back for a couple of years because I set the e-reader on my tablet to black with dark orange letters.

"That blue light won't get me!"

I just now realized that it still casts a blue light on the ceiling when I lay it down.

Eh, even in "the real world" we still encounter blue wave lengths in the evening. I think it is a matter or reduction (aka not shoving a largely blue light source in your face) than elimination.
