I bought these to keep the sun off my front windscreen from hitting my thermostat directly in the summer causing the air conditioning to work more than necessary. Light blue works well because they let in quite a bit of light (darker colors seem to block the light completely to me) and keeps the room cooler in the early afternoon when the sun is shining directly through that window. . If I had bought them for a bedroom I would have bought a darker color but they were perfect for what I had in mind.
