Vijaya PH logo design case study · Healthcare

Forty Years of Trust.
One New Mark.

Two legacies came together. The logo had to carry both.

How we redesigned the identity of Vijaya PH Diagnostic Center after its merger with pH Diagnostic Center, keeping four decades of recognition while looking firmly forward.

Project

Redesign after merger

The brief

Two trusted names. One identity that feels like both.

Vijaya Diagnostic Center has served patients for over 40 years. When it merged with pH Diagnostic Center, the combined brand needed one symbol that long-time patients would still recognise and new patients would see as modern. In healthcare, a logo has to say accuracy and trust before anything else.

The Challenge

  • Two brands, each with its own loyal patients and history
  • A category full of generic crosses, hearts and stethoscopes
  • Patients judge a lab on trust long before they see a report

What Success Looked Like

  • Feels familiar to 40 years of patients
  • Signals precision and accuracy at a glance
  • Looks modern beside national diagnostic chains
  • Works on reports, signage and sample labels

Why it matters

In Healthcare, Trust is the Brand.

Patients choose a diagnostic center on trust. The logo appears on every report, sample tube, receipt and signboard, often small and often in one colour. It has to feel credible instantly and stay consistent across every branch and every document. That takes more than a quick redraw.

Legacy Carried Forward

Four decades of trust, kept recognisable in the new mark.

That’s why the new mark was built to honour the past and lead forward, not just redrawn.

See how we did it

From brief to brand

Two Legacies. One Clear Symbol.

01Strategy

Discover

We met both teams to understand what each brand meant to its patients and doctors. Four words became the filter for every idea: trusted, precise, modern and caring.

02Strategy

Research

We reviewed diagnostic and healthcare brands, local and national. Most relied on crosses, hearts and DNA strands, which made them hard to tell apart.

03Design

Sketch

Explorations around the letter V, checkmarks, shields, gems and lab motifs, looking for one shape that could hold both legacies.

04Design

Explore

Directions were tested on reports, signage and favicons side by side. A V that doubles as a checkmark said “accurate” and “Vijaya” in one move.

05Craft

Refine

We cut the V into diamond facets for a premium, precise feel, and balanced indigo and red so the mark felt clinical but warm.

06Handover

Deliver

Master logo, versions for reports and signage, colour and type system, and organised files for print, digital and every branch.

Behind the scenes

The Ones That Didn’t Make It

Good ideas get cut too. Here’s what we set aside, and why.

Rejected Vijaya PH Diagnostic Center logo idea: The Medical Cross

The Medical Cross

Universally understood, but used by almost every clinic and lab.

Rejected Vijaya PH Diagnostic Center logo idea: The Heartbeat Line

The Heartbeat Line

Caring, but it read as cardiology, not diagnostics.

Rejected Vijaya PH Diagnostic Center logo idea: The DNA Helix

The DNA Helix

Scientific, but cold, and too narrow for a full diagnostic center.

Every detail has a job

Every Facet Carries Meaning

1

The Letter V

The first letter of Vijaya, kept at the heart of the mark so long-time patients still recognise their lab.

2

The Checkmark

The V doubles as a tick: the universal sign for a correct, verified result.

3

Diamond Cut

Faceted edges add precision and value, a quiet signal of accuracy and premium care.

4

Indigo + Red

Indigo for trust and clinical calm. Red for care and the warmth of the original brand.

Construction & rules

Built on Rules, Not Guesswork.

Clear rules keep the identity consistent across every branch, report template, signboard and new partner.

Construction Grid

The facets are built on a consistent angle system, so the V stays sharp and balanced at every size.

Clear Space

Keep a margin of x (the height of the “V”) on every side. Nothing enters this zone.

Stress tests

Tested in the Real World Before Launch.

A logo that only works on a big white screen isn’t finished. We put Vijaya PH Diagnostic Center through the places it actually lives before the client ever did.
