Calm, not quiet
Generous space and soft colour create composure. One precise gesture keeps the work alive.
A working reference for the choices that make Boompah feel unmistakably Boompah—from pearl surfaces and expressive display type to our living signal orbits.
Principles
Use these as a decision filter, especially when a composition starts collecting too many ideas.
Generous space and soft colour create composure. One precise gesture keeps the work alive.
System signals and fine rules meet warm surfaces, plain language, and editorial typography.
The spectrum, motion, and orbit motifs are accents. Their value comes from not appearing everywhere.
Colour
A warm neutral field does most of the work. Pastels carry meaning in small, concentrated doses.
Warm → blush → lilac → sky
Contrast anchor
Ink gives
soft colour a spine.
Typography
Clash Display supplies the character; Manrope keeps the explanation direct and highly readable.

We use plain language, short sentences, and enough room for each idea to land. The tone is capable, candid, and pleasantly unforced.
Interface
Pills belong to actions and small status objects. Content containers stay softly structured, never bubbly.
Actions
Layered, ambient, and built to hold the atmosphere without stealing the message.
Jump to the orbit labComposition
Keep the message on a strong grid. Let the expressive layer crop, overlap, and live near the perimeter.
Do / keep it peripheral
Composition rule
One expressive move per viewport is usually enough.
Actions
Use one primary action per decision area. Secondary and quiet actions should support it, not compete with it.
Variants
States
Forms
Labels stay visible, instructions arrive before the error, and validation explains exactly how to recover.
Field states
Use a work email.
Selection
Use radios for one choice, checkboxes for many, and switches only for settings that take effect immediately.
Radio / one
Checkbox / many
Switch / immediate
Project updates
Email when a milestone changes.
Current state: On
Feedback
Pair every semantic colour with an icon, a plain-language title, and a useful next step when one exists.
A useful note
Supporting context belongs close to the decision it affects.
Changes saved
Confirm completed actions in the past tense.
Review before publishing
Warnings describe the consequence without creating panic.
We could not save this
Keep the user’s input and explain how to recover.
Content patterns
Cards need a clear job, a deliberate hierarchy, and one obvious interactive target.
2.4×
Use one number, one unit, and one sentence of context.
“Clear enough to repeat. Distinct enough to remember.”
Inclusive by default
A specimen is incomplete until it works without a mouse, survives zoom, and communicates change beyond colour.
Keyboard
Every action is reachable and the focus order follows the reading order.
RequiredFocus
Use a persistent 2px ring with enough contrast against both light and dark surfaces.
RequiredTouch
Interactive targets are at least 44 × 44px with space between adjacent actions.
RequiredErrors
Connect messages with aria-describedby; move focus to the summary after submit.
RequiredMotion
Respect prefers-reduced-motion and preserve meaning when animation is removed.
RequiredContent
Buttons use verbs, links name destinations, and icon-only controls have a label.

Signature element
Part interface, part atmosphere. These circles make Boompah’s technical confidence feel warm, patient, and alive.
Live lab
Use the presets as starting points, then isolate layers and push the variables until the right character becomes clear.
Approved voices
Colour, crop, and mark rhythm can shift. The core construction and restrained opacity stay consistent.

Scale & placement
A signal orbit should feel larger than its container. Cropping creates atmosphere; centring makes it feel like a diagram.
