How to use this guide: Start with Skin Tone to find compatible shades, then confirm your developer % and timing in the Color Chart based on hair color and density. Cross-reference the Density Guide to fine-tune processing time, and use the Blending Guide for custom formulas. Skin tone → shade → developer % → timing → blend.

Full Color Chart

All shades with 1.8% and 3% developer results across fine, medium, and full density brow hair.

Pro Tip · Post-Lamination Tinting

Lamination opens the cuticle — meaning color absorbs faster and deeper than on untreated hair. Always drop to 1.8% developer post-lamination regardless of density, and reduce your processing time significantly. Fine/sparse brows: check at 4–5 min. Medium-full brows: 5–6 min max. Front of the brow only: 30–60 seconds. The open cuticle does the work — the developer doesn’t need to.

Cold base, blue-green core — not a true jet black. ⏱ 15–20 min	Fine: Use 1.8% only Medium: Either developer Full: 3% recommended	Cold base, blue-green core — reads as very dark cool brown, not true black. Best for lashes, darkening mixes, or deep cool complexions. Avoid alone on fair skin.

Skin Tone Recommendations

Bronsun stains both brow hair and periorbital skin. Choose a shade that harmonises with the client's complexion.

Fair / Porcelain

Very light skin · Pink or neutral undertone

#5 Light BrownIdeal. Subtle definition without looking harsh on pale skin.

#4 ChestnutGood for light brown brows. Use 1.8% for a soft finish.

⚠ Avoid#1 Deep Black, #3 Blue Black — will look severe on fair skin.

Light / Ivory

Light skin · Warm or neutral undertone

#4 ChestnutPerfect match — cool-neutral brown complements warm ivory tones.

#6 BrownNeutral base, violet core. Add 15–20% #4.1 Red Chestnut to warm the result and prevent any violet surface on lighter skin.

⚠ Use With Care#1 Deep Black — mix with #4 Chestnut, 1.8% only.

Medium / Olive

Beige to olive · Warm or yellow-green undertones

#6 BrownNeutral base, violet core. Warm skin balances the violet tendency — reads as a deep, rich chocolate brown on olive skin.

#7 Dark BrownCool base, yellow-green core. Olive/tanned skin balances the yellow-green — built for this skin tone. May read slightly warm on some complexions.

⚠ Note on Fair Skin#7 Dark Brown alone can pull yellow-green on fair skin. Always add #2 Graphite or correct with #4.1 Red Chestnut.

Dark / Deep

Deep warm or cool brown skin

#1 Deep BlackTop choice. Complements deep skin tones naturally.

#3 Blue BlackStriking on deep cool complexions.

#7 Dark BrownGood when a softer result than black is desired.

Custom Blending Guide

All Bronsun shades can be mixed together before adding developer. Mix dye shades first, then add developer.

How to Read a Ratio

Everything is measured in pumps. Bronsun always uses a strict 1:1 dye-to-developer ratio.

The Rule — Every Time

Step 1: Mix your dye shades · Step 2: Count total dye pumps · Step 3: Add that exact number in developer
Dye pumps = Developer pumps. Always.
