In all honesty, I really hope by blue you don't mean painting calipers and interior items. That is actually a fad that has gone and passed. Single color car, with a single color interior ( black/grey? ) but make sure you have seats that match ( like if you have a grey interior, get black seats ) 
granted, it IS your car, but take a look at what other people have been doing - lately it was jdm
I use 
www.jtuned.com and look under statics as well as the forums under photos only to see what others have done, and I culminate my ideas from there  
 
Granted I'm not out for sponsorship either.
