The color of the projector is only red and green, in tone with the holiday spirit. As this is a laser unit, there is no way to attach a filter to make the lights all white. The idea behind our product is to create a nice contrast with the snow.
However, as we appreciate client input we will put the idea on the list for out next line of products, together with the suggestion to produce an all blue projector with a moving head, as this is also a recurring point of our clients.
