I definitely like color, but I do seem to like my colors solid, so I don't use a lot of multi-colored light strings.
As my wife likes to tell people when explaining how obsessed I am with this, I first started one year after finding a large supply of lights in a KB Toy Outlet in an after-christmas sale. I bought about 4000 lights that day, all of them multi-colored.
The next year, I would sit in my house watching TV and pulling the light bulbs out, re-arranging them into solid color strands.
I still do that some, it's the only way to get orange lights. So I'll take 5 strands of multi-colored lights, and make 1 orange, and sometimes I'll make a couple of blue-green and red-pink light sets (since I can already buy those colors separately, and if you put enough of those together it gives you different "shades" of color.
Merry Christmas.
WOW!
