Choosing a builder gel shade is not just about what looks nice on the website. It is about what works on your nail type, your clients’ expectations, and the finish you’re going for. Cover, sheer, clear, shimmer, milky white, glitter: each one produces a different result on the nail, and picking the wrong one is a frustrating waste of time and product.
Rather than give you a generic guide, we went straight to the data. We looked at 12 months of real Sculptify Builder Gel sales across all shades in the range, and mapped which finishes customers are actually choosing and why. This is what the numbers show.
| All Sculptify shades are HEMA-free and TPO-free. This matters whether you’re a nail tech buying for your salon or a customer managing a sensitive skin situation. The full breakdown of what HEMA-free means in practice is in our acrylates and HEMA explainer. |

Esmea, our crystal clear builder gel, is the single best-selling individual shade. It accounts for nearly a quarter of all individually sold Sculptify units. That tells you something straightforward about how professional nail techs work: they want control.
A clear builder gel works as a blank canvas. It does not alter the natural nail tone, which means the final colour is determined entirely by whatever gel polish goes on top, or by the natural nail if left bare. For nail techs who want maximum versatility, a single clear builder gel serves every client regardless of skin tone, season, or appointment type.
Esmea is also used as an art medium for 3D embossed nail work. Because it cures firm without pigment interference, it holds structure reliably for dimensional designs. If you’re only going to buy one Sculptify shade, clear is the professional default.
When you look across all Sculptify sales, cover and pigmented nude finishes, shades like Wendy and Holly, account for more than four in ten units sold. It is the most popular finish category in the range.
Wendy is a cool pinky nude with pigment behind it, what the industry calls a cover tone. The pigment is there to do a specific job: conceal nail plate discolouration, uneven natural nail tones, or simply give an instant French-adjacent result without needing gel polish on top. Clients who want a “done but natural” result, nails that look healthy and groomed without obvious colour, consistently reach for cover shades.
Holly sits in a similar territory but with a softer, more sheer quality. It is named after Kirsty’s cousin’s wife. The description says it all: if you want a natural-looking nail, this is the one. The distinction from Wendy is opacity. Holly gives a hint of coverage; Wendy actively conceals.
| When to choose a cover shade: Your client wants to wear the builder gel as a standalone finish. They have visible nail plate discolouration or post-gel nail recovery. They want a French-style result without a separate nail polish application. |
Rita and Kelly together make up roughly a quarter of individual shade sales. They are both sheer pink finishes, but they sit in noticeably different positions on the chart above.
Rita is candy floss pink and semi-sheer. It gives a flush of warm pink without the opacity of a cover gel. Kelly is a cleaner, lighter sheer pink that adds a pink hue while letting the natural nail show through. The difference is warmth and saturation: Rita is flirtier, Kelly is quieter.
Sheer pinks are the most popular choice for clients who want something beyond ‘natural’ but are not ready for a full gel polish colour. They also sit well under gel polish top coats when a client wants a subtle base colour warming the final finish.
For nail techs building an initial product kit, Rita and Kelly together cover the sheer pink category efficiently. Having both means you can match to client preference without guessing.
Ella is a milky white soak-off builder gel. It carries a smaller sales share than the natural and nude finishes, but it sells consistently because it serves a specific technique: the baby boomer, also called the ombre French.
The baby boomer is a gradient nail where a soft white blends into a pale pink or nude at the base. Ella is designed exactly for this. It is described as flattering to all skin tones, which is accurate: milky white softens on darker skin tones in a way that a stark white would not.
If you offer baby boomer as a service, or if your clients frequently ask for it, Ella is the shade. If you are building a general-purpose builder gel kit and baby boomer is not in your service list yet, it can wait.
Sarah is a semi-transparent pinky nude with a soft shimmer pigment running through it. It accounts for a solid share of sales, and the reason is straightforward: shimmer in the builder gel itself means the sparkle is structural, not just surface level. It does not chip or wear off because it is cured into the product.
This appeals to clients who always want their nails to catch the light but do not want the maintenance of glitter gel polish on top. Sarah gives a sophisticated shimmer finish that reads well in natural light and under salon lighting alike.
The Flock collection extends this logic further into full statement territory. Quackers, the top-selling Flock shade, is described as “pure party in a pot”: a translucent pink base packed with Mylar shards, iridescent flakes, and multi-sized glitter. The Flock shades sell primarily as gift sets and event choices rather than everyday salon staples, which is reflected in the chart.
The chart above gives you the landscape. Here is how to translate that into a decision:
Choose Esmea (crystal clear). It will not compete with or alter any colour you apply over it, and it is the most versatile shade in the range for mixed-service nail techs.
Choose Holly for a sheer, natural finish, or Kelly for a light sheer pink warmth. Both work without any gel polish on top.
Choose Wendy. The cool pinky nude pigment conceals discolouration and gives a clean, finished result as a standalone application. Our acrylates article explains how HEMA-free formulations are especially important when applying builder gel over recovering nails.
Choose Rita for a semi-sheer candy floss pink, or Kelly for something lighter. Rita is warmer and slightly more visible; Kelly is subtler.
Choose Ella (milky white). It is specifically designed for this technique and works on all skin tones.
Choose Sarah for a refined shimmer in a pinky nude base, or explore The Flock collection for full glitter and Mylar finishes when the brief calls for something more statement.
Whatever shade you choose from the Sculptify range, the formulation is consistent: every shade is HEMA-free and TPO-free. This is not a niche feature. HEMA (hydroxyethyl methacrylate) is the ingredient most commonly linked to nail product sensitisation, and the professional industry has been moving away from it for several years.
For nail techs, working with HEMA-free builder gel reduces the risk of sensitising your clients over repeated applications. For home users, it is relevant if you have had reactions to other gel products in the past.
All Sculptify shades are also vegan and cruelty-free. The full explainer on what HEMA-free means, which other ingredients are worth knowing about, and how sensitisation develops is in our dedicated acrylates and nail product ingredients guide.
If you’re new to builder gel and want to understand the difference between builder gel and gel polish before choosing a shade, that’s a good starting point.
A clear builder gel has no pigment and cures to a transparent finish. It adds structure and strength without changing the nail tone. A cover builder gel contains pigment designed to conceal the natural nail plate, producing an opaque or semi-opaque finish. The choice depends on whether you want the builder gel to act as a canvas or as a standalone colour.
For a ‘natural nails but stronger’ result, Holly or Wendy are the most popular choices. Holly gives a very soft, sheer finish. Wendy provides more coverage for nails that need some evening out.
Yes. All Sculptify shades can have gel polish applied over them. If your intention is always to use gel polish on top, Esmea (clear) is usually the most practical choice as it does not add any underlying tint.
Yes. All shades in the Sculptify Builder Gel range are HEMA-free and TPO-free, as well as being vegan and cruelty-free. For more information on why this matters, see our guide to acrylates in gel polish.
Esmea (clear) works universally as it does not add any tone of its own. Ella (milky white) is also described as flattering on all skin tones, particularly for baby boomer techniques. Sheer pinks like Kelly can read differently on lighter versus deeper skin tones, so matching the pink warmth to the client’s undertone is worth considering.
BIAB stands for Builder in a Bottle and refers to a brush-on format of builder gel rather than a fundamentally different product. Sculptify is Kirsty’s brush-on builder gel system. The full explanation is in our builder gel explainer article.
