Finishes
Five finishes. One shape.
Every case is the same 6061-T6 billet, bead blasted and Type II satin anodised. Anodising puts the colour into the metal rather than on top of it, so it does not chip off an edge the way paint or powder coat does.
Space Gray
Deep. Understated.

Silver
Bead-blasted satin.

Midnight Blue
Dark. Quiet.

Rose Gold
Warm. Distinguished.

Crimson Red
Bold. Unapologetic.

The finish is cosmetic only. Dimensions, weight, slot count and the MagSafe module are identical across all five, so the choice costs nothing but preference. Full figures are on the specifications page.
