a darker skin might be nice. its hard to say without being ble to see what your thinking lol.
maybe a simple dark base with one solid, contrasting colour that stands out against it for like text and outlines etc.
i always thought the Buzzer Beat colours - Black, Pink, and green/yellow (i forget) - were really good cos, although you wouldnt think the colours went together really well, the pink and green/yellow were really bright and stood out against the black so it immediately caught your attention. All the promotional stuff for the drama really looked good
