Why Do Darker Skin Tones See Fewer Foundation Undertone Options?
The beauty industry has expanded depth ranges significantly since 2017, yet undertone variety within deep shades remains severely limited. According to the Benchmarking Company, 77 to 83 percent of consumers with deeper skin cite limited undertone options as their primary frustration. This gap reflects formulation challenges with high pigment loads, pigment sourcing constraints for cool and olive tones, and commercial calculations that prioritize stability over variety.
The beauty industry has made meaningful progress on shade depth since Fenty Beauty's 40-shade launch in 2017. Yet the undertone gap within deep shades persists as a structural problem, not a marketing oversight. Higher pigment loads required for deep foundations create stability challenges that disproportionately affect cool and olive undertones. Commercial forecasting models treat edge-case undertones as unprofitable, creating self-fulfilling low-demand prophecies. On-demand manufacturing technology offers a path forward by eliminating the forecasting constraints that currently limit undertone variety. This post examines the chemistry, economics, and consumer impact of the undertone gap, and why structural solutions matter more than incremental range expansion.

What Is Foundation Undertone and Why Does It Matter?
Foundation undertone refers to the subtle color beneath the surface of your skin that determines how a foundation shade appears once applied. The three primary undertone categories are warm (yellow, golden, or peach), cool (pink, red, or blue), and neutral (a balance of warm and cool). Olive undertones, which require a careful balance of yellow, red, and subtle green or gray pigments, represent a fourth category that many brands fail to address.
Undertone matters because it determines whether a foundation appears natural or artificial on the skin. A foundation with the correct depth but wrong undertone can create an orange cast, gray mask, or ashy appearance that is visible in natural light. For consumers with deep skin, this mismatch is particularly noticeable because higher pigment loads amplify any undertone error.
The distinction between overtone (surface color) and undertone (subsurface color) is critical for accurate foundation matching. Surface color changes with sun exposure, skincare, and time. Undertone remains constant. This is why two people with the same surface depth may need completely different foundation shades based on their underlying coloration.
Why Undertone Options Shrink in Deeper Foundation Shades
Creating foundation for deeper skin tones requires higher pigment loads. The iron oxides, titanium dioxide, and organic pigments that provide coverage must be used at higher concentrations to achieve depth without ashy or gray results. Higher pigment loads create stability challenges. Pigments can separate, oxidize, or shift color over time.
Warm undertones, which rely on red and yellow iron oxides, are more stable than cool undertones, which require blue and green pigments that are harder to suspend and more prone to migration. According to Elchemy's technical analysis, iron oxides provide the pigmentation foundation for virtually all color cosmetics. The three primary shades (red CI 77491, yellow CI 77492, and black CI 77499) blend to create every foundation shade available globally. Red iron oxide accounts for 38.2 percent of the iron oxide for cosmetic pigments market because it provides warm undertones essential for medium to deep skin tones.
Olive undertones, which require a careful balance of yellow, red, and subtle green or gray pigments, are among the most difficult to formulate at depth. The green family pigments needed for olive tones are scarce in cosmetic-grade formulations and expensive to source. Brands facing cost and stability constraints often default to warm and neutral undertones in deep shades, leaving cool and olive consumers without options.
The inclusive shade pigment systems market for deep skin tones is projected to grow from $163 million in 2026 to $378.9 million by 2036, reflecting increasing investment by global brands in deeper shade development. However, historical growth was constrained by limited pigment availability and undertone instability.
The Commercial Calculations That Limit Undertone Variety
From a commercial perspective, deep shades with complex undertones represent a smaller addressable market. A brand may calculate that a deep cool shade will sell a fraction of the units that a deep warm shade sells. The minimum order quantities for pigment sourcing, the formulation development costs, and the shelf space requirements make edge-case shades economically unattractive under traditional manufacturing models.
This calculation creates a self-fulfilling prophecy. The brand does not offer the shade. Consumers who need it cannot buy it. The brand sees no sales data supporting the shade. The brand concludes there is no demand. In reality, the demand exists but cannot be expressed through purchases because the product is unavailable.
Raw materials and packaging typically account for 40 to 50 percent of overall production budgets for beauty product manufacturing. High raw material costs and formulation complexity restrict adoption of inclusive shade systems in entry-level product lines. Regulatory approvals for pigments differ across regions, adding operational oversight. These factors lead to selective deployment where shade inclusivity justifies incremental cost.
The Consumer Impact of Limited Undertone Options
The undertone gap has measurable consequences. According to the Benchmarking Company's March 2026 survey of more than 4,300 US females, 61 percent of participants with darker skin tones state they have abandoned a specific brand because they felt the brand's shade lineup was not inclusive. Seventy-seven to 83 percent of deep and dark skin consumers cite limited undertone variety in deeper shades as a primary frustration.
The practical result is that consumers with deep skin and cool or olive undertones often purchase shades that are too warm, creating an orange or red cast that is visible in natural light. They may use color correctors or mix multiple products to achieve an acceptable result. This workaround is expensive, time-consuming, and ultimately unsatisfying.
Fifty-three percent of Black consumers report difficulty finding beauty products that match their skin tone, according to Mintel data cited by Arbelle. Black consumers are 5.7 times more dissatisfied with makeup offerings compared to non-Black consumers, per McKinsey & Company. Inclusive beauty brands grew 1.5 times faster than their less inclusive competitors in 2024, according to Circana.
How On-Demand Manufacturing Changes the Equation
On-demand manufacturing eliminates the commercial constraints that limit undertone variety. A system that creates custom shades at the point of purchase does not need to forecast demand for specific undertone combinations. It does not need to manufacture thousands of units of a deep olive shade in advance. It simply creates the shade when a consumer with that undertone requests it.
This model transforms economics. The cost of offering 40 shades versus 400 shades becomes nearly identical because the system uses the same base pigments in different ratios. No shade is an edge case because every shade is made to order. For consumers who have been told their undertone is too rare to warrant a dedicated product, solutions like on-demand manufacturing offer a fundamentally different approach.
The inclusive shade pigment systems market reflects this shift. Forward expansion is supported by improved chromatic precision, better dispersion stability, and structured shade mapping approaches adopted across global product portfolios. As inclusive pigment systems become standard inputs in global beauty brand development, the structural barriers to undertone variety begin to dissolve.
