Can i change the color of my dash lights?

Some of my dash lights have gone out and are dim. I wanna change the color to blue but im not sure if the lights in the dash of my 95 Honda Accord emit light by using bulbs or a colored cover. Also where can i purchase this?|||I have orange ones in my Dakota dash and courtesy lamps I forgot what I paid but they are little slip over covers that go onto each bulb .I bought them at Auto-zone .
