Choosing a plaster color is a little different from choosing paint. A hand-troweled lime finish isn't one flat color. It has soft movement, slightly lighter and darker areas, and it changes with the light through the day. That is the beauty of it, and it is also why a tiny paint swatch on a screen won't tell you the whole story.
Color Skim comes in 34 shades, grouped into five families. This guide shows you how to narrow them down: start with a family, read the undertone, think about your light, then sample.
Step 1: Start with a family
Each family gathers shades with a similar character. Pick the one or two that match the mood you're after.
Whites & Creams
Soft, light shades for rooms that should feel airy and calm. This family runs from cooler, stony whites to warm, honeyed creams:
- 121 Chalk: a luminous, softened mineral white, not stark
- 146 Stria: a quiet, stony off-white with a balanced, silty undertone
- 124 Intonaco: linen white with a subtle bone-like warmth
- 137 Calcite: a warm parchment white with a creamy undertone
- 145 Vestige and 138 Albarium: soft bone whites with silty warmth
- 148 Ionic, 128 Kashan and 149 Arezzo: the warmest of the family, from honeyed cream to golden ochre and pale peachy terracotta
Warm Earth & Clay
Grounded, earthy shades that make a room feel warm and settled:
- 143 Albite: a soft, sun-washed tan with a peach-to-bone undertone
- 125 Tivoli: a warm stone-wash tan
- 140 Quoin: a mid-tone warm stone-grey
- 129 Jura: warm gold between rich sand and toasted ochre
- 150 Ostia: faded terracotta with a dusty-rose undertone
- 130 Lutum and 122 Argil: deep earth tones between toasted umber and terracotta
Stone & Greige
Balanced neutrals that sit between grey and tan. They are the most flexible whole-house choices:
- 139 Tuffeau: a light sandy beige with a mineral-grey undertone
- 147 Pediment: a balanced cool-mineral grey
- 126 Trass: a calm greige between cool grey and warm tan
- 151 Cornice: a mid-tone warm taupe
- 144 Terron: a medium, earthy greige
- 127 Galet: a cool river-stone grey
- 132 Flysch: a muted tan with a greenish-grey undertone
Cool Greys & Blues/Greens
Crisp, calm and modern:
- 134 Ferro and 153 Monolith: balanced, true neutral greys
- 152 Zinc: a steely blue-grey
- 154 Shale: a sage stone-green
- 136 Gneiss: an olive-inflected grey
- 133 Caelum: an atmospheric slate blue
Deep Accents
Dramatic, enveloping shades for feature walls and intimate rooms:
- 123 Breccia: a deep taupe with an olive-brown undertone
- 131 Klinker: an iron-rich red-brown
- 141 Glacis: a shadow-stone grey with a brownish-umber undertone
- 135 Tephra: a deep grey with a brownish-mauve undertone
- 142 Galbe: a deep slate grey with a violet-blue undertone
Step 2: Read the undertone
Two colors can look alike at first glance and feel completely different on the wall because of their undertone, the hint of another color underneath. On every Color Skim product page, the color description names the undertone. A few examples:
- Warm (yellow, gold, peach, rose): Kashan, Ionic, Arezzo, Ostia and Albite. These glow in warm light and pair naturally with wood, brass and terracotta.
- Balanced or silty: Stria, Trass, Terron and Pediment. These shift gently with the light and are easy to live with in every room.
- Cool (blue, green, violet): Zinc, Caelum, Galbe, Shale and Gneiss. These feel calm and fresh, and pair well with stone, steel, linen and greenery.
- Earthy brown or olive: Breccia, Flysch, Glacis and Tephra. These feel grounded and architectural.
Tip: hold your top choices next to something you are keeping, such as a floor sample, cabinet door, sofa fabric or stone countertop. The undertone that harmonizes with your fixed finishes is usually the right one.
Step 3: Think about your light
Plaster responds to light more than flat paint does. Trowel movement catches light and shadow, so the same color can look lighter, darker, warmer or cooler through the day.
- North-facing rooms get cooler, softer light. Warm whites and creams (Intonaco, Calcite, Ionic) or warm earth tones can balance it. Very cool greys may read colder.
- South-facing rooms get warm, bright light that can intensify warm shades. Balanced neutrals and cooler shades stay crisp.
- East and west rooms change a lot between morning and evening. Sample at both times.
- Artificial light: warm bulbs push colors warmer, cool bulbs push them cooler. Check samples under the bulbs you will actually use.
- Raking light (light skimming across a wall from a window or sconce) shows the most trowel movement. Deeper shades show movement most clearly.
Step 4: Consider sheen
Sheen changes how color reads. A matte, unburnished Color Skim finish looks soft and velvety. Burnishing the final coat increases sheen and depth, and Gloss or Low Gloss sealer also adds sheen. More sheen generally makes a color look a touch richer and shows more reflection. On low-touch walls you can skip sealer to keep the most matte look. See Gloss vs Low Gloss vs No Sealer.
Step 5: Build a palette
Many projects use two or three Color Skim shades: one for most walls and a deeper or contrasting shade for a feature wall, powder room or adjoining space. Some easy starting combinations:
- Soft and airy: Chalk + Intonaco + Stria
- Warm Mediterranean: Ionic + Arezzo + Ostia
- Earthy and grounded: Albarium + Tivoli + Argil
- Calm and modern: Stria + Ferro + Monolith
- Organic green: Galet + Shale + Gneiss
- Moody evening: Pediment + Galbe + Tephra
Each product page also suggests pairings in its "About" section.
Step 6: Sample on your wall
This is the most important step. Order 2″ color chips for $5 each for your shortlist (three to five is a good number). Each chip is real Color Skim plaster on a 1/8″ thick wood chip, so you see the actual material, not a printed swatch.
- Place chips on the actual wall, at eye level and near the floor.
- Look at them in morning, midday and evening light, and under your lamps.
- Put them next to your floor, trim and fabrics.
- Step back across the room. Plaster is seen at a distance more often than up close.
- Narrow to one or two, then use the "See it in a room" visualizer on the product page to imagine the full effect.
Step 7: Plan quantities
Once you've chosen, plan on about 50–75 sq ft per gallon kit for two coats. Gallon Kits are $96 and Quart Kits are $32. The project calculator on each product page works out how many you need. If you are using more than one color, measure each area separately.
Common questions
Will my wall match the chip exactly?
Hand-troweled lime plaster always has some natural variation in tone and movement. That is part of its character. Your technique (number of coats, burnishing, sealing) also affects the final look. Because chips are real plaster, they show the true color and character of the material. A sample board made with your own technique (coats, burnishing, sealer) shows exactly how your finish will look.
Which colors show the most movement?
Mid-tone and deeper shades show trowel movement most clearly. The lightest whites show it as a quiet, subtle shift.
Can I use different colors in adjoining rooms?
Yes. Choosing shades from the same family, or with similar undertones, keeps the flow between rooms smooth.
