Brand foundations for logo design

A precise, engineered blue for a circuits & modules store.

Everything a designer needs to build a logo that sits naturally inside the product: the exact palette, the type, and the shape & elevation language. This page is rendered in the system it documents — the mark, colors, radii, and shadows you see are the real tokens.

01

The logo brief

The store sells electronics components and modules — the working headline is “Circuits & modules for your next build.” It serves builders and makers in Bangladesh, prices in Taka (৳), and pays cash on delivery, nationwide. The brand name is not yet finalized (currently “Store”).

Personality

Technical Precise Modern Trustworthy Approachable Utilitarian

Direction

  • Lead with the brand blue. One confident, saturated blue — no gradients-as-crutch, no second brand hue competing with it.
  • Shape language is engineered, not soft. Corners are tight (≈6px feel) — geometric and deliberate, never pill-round and never knife-sharp.
  • Motif to explore: a chip / circuit node, a module outline, a connector, or a clean monogram — geometry that reads at 24px favicon size and in one flat color.
  • Must survive: single-color (black & white), tiny sizes, and both light and dark grounds.

Avoid

  • Photoreal wires, cluttered PCB traces, or 3D bevels.
  • Rounded “friendly blob” marks — off-brand for a precision-tools store.
  • A second accent color fighting the blue.
  • Thin hairline detail that vanishes at favicon scale.

Placeholder mark

The rounded-square chip glyph in the header is a starting sketch built from these tokens — a reference point, not the final answer.

Color

Blue primary on cool, near-neutral surfaces. Neutrals carry a faint cool bias rather than pure grey. Values are authored in OKLCH (source of truth); hex is an approximation for tools that need it. Each swatch shows the light and dark value side by side.

Typography

One family, Inter, does display and text — loaded via next/font. Tight negative tracking on large sizes; generous line-height in body. Digits use tabular figures wherever prices align.

Shape & radius

Tight, calc-based scale off a 0.375rem (6px) base. Deliberately restrained — corners are softened just enough to feel finished, never rounded enough to feel playful. This is the single most important cue for the logo's corner treatment.

Elevation

Shadows are subtle and tight — a soft 10%-black wash, not a dramatic drop. Depth comes from layering surfaces, not heavy shadow.
