In Rainbows, as a title, implies a sense of comfort and delightfulness.
Symbolically, rainbows are more likely to be associated with kittens and warm blankets than the grim and glum circumstances Radiohead is known for soundtracking.
There's a slight, if expected, twist at play. The band is more than familiar with the unpleasant moods associated with colors like red, green, and blue -- all of which, of course, are colors within a rainbow -- all of which are present, and even mentioned, during the album.
The album is very song-oriented, with each track constantly moving forward and developing, yet there are abstract electronic layers and studio-as-instrument elements to prevent it from sounding like a regression.
In Rainbows will hopefully be remembered as Radiohead's most stimulating synthesis of accessible songs and abstract sounds, rather than their first pick-your-price download.
