Yeah if you like the blue colors then you should keep a few blue actinic bulbs on there. However, keep in mind that plants also use light from the red spectrum to photosynthesize.

Also, those white lights you have are actually green light being emitted which is how we humans perceive brightness. However, plants are green because they reflect green light meaning that they do not use it at all. White lights = Makes your tank look bright and vibrant but does not aid in plant growth.
