Colored lights. I do not like all white lights. However, when doing colored lights when I used to decorate, I did not put up strings of mixed colored lights. Because from a distance, they blend together to make white or almost white. What I would do, is put up strings of all one color. For instance. One tree all green, another all blue, trim of the house all red, etc. I also used colored spot lights. I did use some white lights a few times in a couple trees, but would enhance the same tree with a colored spot light.
