SharpBrain.app · Brand & design guide · v0.1

Serious about your brain. Not serious about itself.

A direction for busy people 18 to 35: clinical confidence in the type and layout, playful energy in the shapes and accent colour. Geometric pieces are the recurring motif, standing in for games, puzzles and neurons.

01 · Logo
SharpBrain

Four geometric pieces on a dark tile: a dot, two quarter-rounds, a block. Each piece doubles as a game category icon. The wordmark is Sora Bold, tracked tight; “Brain” picks up the primary violet. Horizontal lockup for web, mark alone for the app store and favicon.

02 · App icon

Full-bleed dark tile, no wordmark. The lime dot gives it one bright point that reads at 40px on a home screen. Pieces sit on a 6-unit grid with a 12-unit inset; the OS applies the corner mask.

Round 2 · App icon alternatives

Four marks, same palette

2aPuzzle pieces (current)

Most “game”. Four pieces map to four categories. Least literal about the brain.

2bTwo hemispheres

Abstract brain: two lobes, a split down the middle. Reads as “brain” instantly, still geometric.

2cS monogram

Letterform on violet. The lime dot is a synapse firing. Most premium, least playful.

2dNeuron

Most “science”. A node lighting up. Can animate on launch. Thinner details soften at 40px.

Ratio

70% Mist and white, 20% Ink, 8% Violet, 2% Lime. Lime is for one thing per screen: the streak, the score, the primary CTA on dark.

Pills everywhere; 24px corners on cards, 16px on tiles. Shadows only on things that float (the phone, the app icon). Everything else is flat.

Ink and Mist swap roles. Violet moves from button to hero card in dark mode so the primary CTA becomes Lime (13.8:1 on Ink). Lavender replaces Violet for small shapes on dark, where Violet drops below 3:1. Lime stays the one accent in both modes. This site applies the same mapping under your system appearance.

Brand-first: the four puzzle pieces become the hero. Louder, more consumer, better for ads and social. The live home page combines 1a's structure with 1b's shape tiles and the Playverse layout.
