The colouring of this is similar to the colouring of the pink floyd album (see below). This could be to get Pink Floyd fans to support them. Pink Floyd have a massive fan base and this could be a good idea to tap into that fan base.
The front cover doesn't show the band members, but instead shows one man that appears to be on a golden path. This could be a visual metaphor to show that this man (could be representing their group) are on their path to glory.
The name of the band, Muse is in their standard font with a line above and below the name. This is kept standard from album to album, which lets fans know what to look out for in an album cover.
The album name is in the corner and is out of the way and attention is not drawn to it (because the image in the centre has attention drawn to it). However, the background is white and the band name/album name is easily visible because of the white background.
The back cover shows all members of the band in a washed out black and white effect. They appear to be walking along a path, which could be a reference to the front cover. They are dressed in fairly casual wear that is quite 'rocky' and they look quite 'cool'. The image of them is quite blurred to the viewer can not see their faces. This could be to hide their identities or just for visual effect.
The track list is on the top right of the back and attention is drawn to this as it is in colour, whereas the rest of the back cover is in black and white. The colouring of the track list is different colours of the rainbow, which is a reference to the front cover.
The bar code is quite large and sticks out at the bottom of the back cover. The legal things are around the barcode, which is pretty standard as digipacks go.
The disk is all white and doesnt stick out as much as the front cover does. The standard Muse sign is on the right with the album name just below. Attention is drawn to the band name, which shows that the band want to show the name of the band more. The legal 'stuff' is on the left which shows who they are signed to.
There is a similar pattern on the disk as there is on the front, except (as stated earlier) on the disk, the pattern is not coloured in.
