Brand Color Harmonizer

The team-photo cohesion problem

Modern company About pages and team grids put 5-50 headshots in a single visual block. When the photos were shot at different times — different photographers, different lighting, different cameras — the grid looks haphazard. Some photos are warm, some cool. Some are saturated, some flat. The eye notices the inconsistency before it notices the people.

The traditional fix is sending all the photos to one retoucher who hand-grades them to match. That works but is slow and expensive. The cheap, fast version: apply a subtle brand-colour tint to all of them. Every photo now leans the same direction. The grid reads as cohesive even though the individual shoots were different.

What this tool does (pure pixel math)

The harmonizer applies a soft-light-style blend pulling each photo's highlights toward your brand colour. The formula:

output_rgb = source_rgb × (1 - strength × luminance) + tint_rgb × (strength × luminance)

Brighter pixels (highlights) get more of the tint; shadow pixels stay mostly unchanged. This avoids the muddy cast you'd get from straight alpha-mixing (which tints everything uniformly and makes dark areas look gray). Total processing time: sub-300 ms on our worker — the no-model, no-network operation that exists. Pure numpy.

Recommended strengths

• 5-10% — almost invisible per-photo; visible cohesion across a team grid only.
• 10-18% — sweet spot. Subtle on individual photos, clearly cohesive in a grid. Default.
• 20-30% — visible brand colour in highlights. Use for explicit brand-style photo treatments (campaign material).
• 30-40% — strong tint. Photos start to look filtered. Use sparingly.
• 40%+ — colour cast becomes the dominant feature. Almost always too strong for team grids.

Use cases

• Company team grids. Unify mismatched headshots from years of hires.
• Conference speaker grids. Match 20 speakers shot in 20 different lighting setups.
• Editorial author photos. Pull all contributors toward the publication's brand palette.
• LinkedIn campaign banners. Match cover photos across a marketing team.
