Are you wanting to use the lights as mainly atmosphere, or accents? I guess a lot depends on where your decorations & props go, both interior & exterior. Just as one example, I like to twist one string each of purple and orange together and hang them from archways or in the window; it gives a nice glow when hung behind black cloth. Would love to here your decor ideas/themes.
Hope it helps - good luck!
