I normally like blue, but this shade reminds me of the blue screen that shows up when windows screws up, so green.
I like green... but i think green is not a primary color... just a secondary color... because Green = Yellow + Blue
You can consider primary colors in many ways but yes, you cab get green from yellow plus blue... "Media that combine emitted lights to create the sensation of a range of colors are using the additive color system. Typically, the primary colors used are red, green, and blue." http://en.wikipedia.org/wiki/Primary_color
Blue for me (except in reference to my website). BTW here's an acronym to remember spectrum colors: VIBGYOR (violet, indigo, blue, green, yellow, orange, red). I got that over half a century ago from a comic book, and it has stayed with me ever since then.
