All Interior lights to blue

Someone told me to get blue lights. Do they have them for all the interior lights? (ex. the little green light thats on the knob for the fog lights,the lights for the ac/heat, the lights for the temp.control are green also) I want all that has a green color light in the interior to be blue. If this is at all possable can someone help???????

usually it is not the bulb that makes the instruments light up different colors. all the stock bulbs are clear. there is a piece of colored plastic behind them that the bulb goes into that changes the color. i don't know of anyway to get those in different colors
