Brunette Basics: How To Formulate For Warm + Cool Tones
Let’s talk brunettes. Unsure what to reach for when you want to see a cooler effect, blended warmth or a multi-tonal blend? Here’s how to avoid unwanted reds, greens and muddy browns—by understanding a few simple backbar rules! We’re dropping some formulation knowledge on the major differences between neutral and natural, why it matters and how to formulate for a diverse range of brown-based blends.
Keep scrollin’ for this total brunette breakdown from PRAVANA Artistic Regional Educator Tim Bo Mack (@timboplease).
The Difference Between Naturals & Natural Brunette Results:
- Naturals (N): Cooler Effect
- Blended Neutrals (Nt): Blended Warmth
- Neutral Lowlights (NtL): More Warmth With Softness
Why This Is Important:
As a colorist, you need to understand how to utilize all three primary colors—blue, red and yellow—to create custom formulas for your guests. So, let’s break down how these different tonal values impact color results using PRAVANA ChromaSilk Blended Neutrals, Naturals and Neutral Lowlights.

Here’s Why Naturals Are Cool-Toned:
Naturals are equal parts of all three primary colors. When red and yellow mix, they create orange—so you’re left with blue and orange that NEUTRALIZE each other. But, blue is the more dominant color and there’s not enough warmth in the orange to overpower the blue pigment, so this creates a cooler-toned color.
Add Warmth For Neutral, Brown-Based Blends:
While Blended Neutrals use the same primary colors as Naturals, there are added red and yellow tones. This means = more blended, warmer tones to overpower the dominant blue pigment that create neutral, brown-based colors.
Less Formulas, More Dimension: Blended Neutrals are pre-mixed permanent shades (Levels 3 to 7), that make formulating for dimension less complicated. This will help you reduce the amount of time and color boxes used at the backbar.

Neutral Lowlights
Neutral Lowlights create soft dimension by tinting-back and filling at the same time to create a more natural-looking lowlight on extremely blonde, porous hair.
Break Up Solid Brunettes With Dimension:
Gray coverage clients looking for a multi-dimensional result? Adding Blended Neutrals creates a subtle contrast that’s KEY to avoiding the solid-color-all-over look that gray coverage can sometimes create.
