The light in late August isn’t yellow. It’s more complicated than that and so is this palette.
Welcome back to Color Lab, where we slow down, pay attention, and get deeply weird about color. We’ve fallen for a single moody pigment (hi, Perylene Green), buried a tube of Mummy Brown in the metaphorical garden, and traced purple back to some very unlucky sea snails. Today we’re doing a Palette Builder (our third one, see Color Lab #2 and #4 for Spring Garden and Winter Neutrals) and the season we’re chasing is that specific, golden, slightly exhausted light of late summer.
You know the one. Not the bright, hopeful yellow of June, but the heavy, honeyed, low-angle glow of late August, when everything’s a little sun-bleached and the shadows have gone long and blue. That light is made of neutrals and neutrals are where color mixing gets genuinely nerdy. Let’s build it!
First, a Word About Why “Muted” Is Harder Than “Bright”
Making something bright is easy. You squeeze it out of a tube. Making something beautifully muted (a neutral with life in it, a gray that’s secretly warm, a tan that glows) that’s the advanced move. Dead, muddy neutrals happen when you mix without intention. Living, luminous neutrals happen when you understand what’s actually in the tube.
Late-summer light is all about those living neutrals: sand, dry grass, weathered wood, hazy sky, warm stone. So instead of reaching for pre-mixed browns and grays (which tend toward flat and lifeless), we’re going to build ours from pigments that bring their own personality, warmth, granulation, transparency, and a little bit of unpredictable magic.
The Yellows: Warm Is Not the Same as Bright
Naples Yellow Hue (Like our old friend Sap Green from Color Lab #4, this is usually a blend along the lines of PW4 + PY97 + PR101. We did find one brand, M Graham, that was a single pigment PBr24.) is, quite simply, sunlight in a tube. It’s a soft, opaque, slightly peachy pale yellow with a lovely chalky quality, and it’s the backbone of any sun-washed palette. Where a bright lemon yellow shouts, Naples Yellow glows. It’s the color of warm stone, pale sand, and afternoon light on a wall. (Historically real Naples Yellow was a lead-antimony pigment; the modern “Hue” versions are safe blends that capture the same gentle, opaque warmth. Same vibe, no heavy-metal drama.)
Indian Yellow (PY150 in the modern version) is deep, transparent, and glowing. A golden, almost amber yellow that behaves completely differently from an opaque one. Thin it out and it’s pure late-day sunlight; layer it and it builds this honeyed depth that opaque yellows simply can’t. It’s the difference between light on a surface and light coming through something.
The Earth Tones: Where the Palette Comes Alive
Monte Amiata Natural Sienna (PBr7) is the nerd’s sienna, and it’s here to teach us something: natural pigments behave differently than synthetic ones. Named for the mountain in Tuscany where it is from, it’s a genuine earth pigment and here’s a fun wrinkle: PBr7 is the same index code as Burnt Sienna, Raw Umber, and a whole family of earth colors. They look nothing alike, because a natural earth’s color comes from where it was dug and how it was roasted, not from a tidy lab formula. One code, a dozen personalities. It’s a slightly variable, granulating, characterful mineral that settles and separates in ways a synthetic pigment never will. It gives you gorgeous, slightly gritty, organic golds and tans that feel like they came from the actual ground. Because they did.
Transparent Red Oxide (PR101) is our returning champion (you’ll remember it from mixing “Mummy Brown” alternatives and building sophisticated purples, this pigment gets around). PR101 is synthetic red iron oxide, and depending on how it’s heated it can come out anywhere from bright brick to deep transparent brown, this transparent, glowing version is the good stuff. Here it’s doing the work of heat, rust, and warm shadow. Transparent and staining, it glazes beautifully over the yellows to deepen them into that sun-baked, terracotta warmth, and it’s the secret to shadows that feel warm rather than cold. The shadows you actually see on a hot day.
The Cool Notes: Shadows, Depth & a Little Chaos
Ultramarine Blue (PB29) is our one true cool, and it’s essential. A palette of pure warm tones reads flat, but drop in a blue and suddenly you have contrast, and contrast is what makes warmth feel warm. Ultramarine is the color of late-summer shadows and hazy distance, and it’s a natural granulator, so it settles into paper texture with a beautiful grainy quality. Mix it with Transparent Red Oxide and you get that whole family of complex, muted violet-grays we love for shadow.
Lunar Black (PBk11, or any granulating black) is the wild card, and it’s the most fun pigment on this list. Here’s the nerdy delight: instead of laying down as a flat, dead black, Lunar Black granulates dramatically. The pigment particles clump and repel and settle into the paper’s valleys (Some artists fight it. We frame it and put it on the wall), creating a mottled, textured, crater-like effect all on their own. Use it in a sky and you get texture that looks like weathered stone or a stormy haze. It does the work for you.
The Whites: Two Very Different Jobs
Titanium White (PW6) is your straightforward opaque white — powerful, bright, and perfect for sun-washed tints. Add a touch to any of the colors above and you get those pale, dusty, sun-faded versions that live all over a late-summer landscape. It’s how you take Naples Yellow from “warm” to “bleached by August.”
Buff Titanium (PW6:1, note the colon; it’s a warmer, off-white variant of the same titanium base as plain PW6) is the sleeper hit of this entire palette, and if you’ve never used it, this is your sign. It’s a soft, warm, pinkish-tan off-white. Essentially a “dirty” white with a built-in earthy warmth. It is perfect for sun-bleached neutrals: driftwood, dry sand, faded stucco, bleached grass. Mix it into anything and it mutes and warms simultaneously, knocking the freshness off a color in the loveliest way. Where Titanium White brightens, Buff Titanium ages.
The Palette at a Glance
For the pigment-nerds (hi, us) and anyone building this from tubes, here’s the whole thing with codes. Some versions may use different blends, so always check the tube (here’s a super handy resource for checking pigment codes).
- Naples Yellow Hue — PW4 + PY97 + PR101 (blend, almost always a blend)
- Indian Yellow — PY150
- Monte Amiata Natural Sienna — PBr7
- Transparent Red Oxide — PR101
- Lunar Black — PBk11
- Ultramarine Blue — PB29
- Titanium White — PW6
- Buff Titanium — PW6:1
Swatching the Palette (This Is the Fun Part)
Squeeze all eight out and swatch them full strength first, so you know each pigment’s true voice. Then start playing!
- Test the granulators solo. Lay down big juicy washes of Lunar Black, Ultramarine, and Monte Amiata Natural Sienna and let them dry completely without touching them. Watch how the particles settle.
- Build your neutrals on purpose. Transparent Red Oxide + Ultramarine gives you warm-to-cool shadow grays depending on the ratio. Naples Yellow + a whisper of Transparent Red Oxide gives sun-warmed stone. Everything + a little Buff Titanium goes instantly sun-faded.
- Glaze the transparents over the opaques. Layer transparent Indian Yellow or Transparent Red Oxide over dry opaque Naples Yellow and watch depth appear.
- Find your sun and your shadow. For this palette, “sun” lives in Naples Yellow, Indian Yellow, and Buff Titanium; “shadow” lives in Ultramarine, Lunar Black, and Transparent Red Oxide. Almost any late-summer scene is just a conversation between those two groups.
Pay attention to which colors granulate, which stain, which stay put, and which lift back off. That’s the personality of your palette, and knowing it is the difference between fighting your paints and dancing with them.
Why This Palette Works (The Nerdy Takeaway)
Notice what we didn’t include: no bright primaries, no pure black, no pre-mixed browns. This palette is built almost entirely from warm neutrals, earth pigments, and granulators, anchored by a single cool blue. Real sunlight isn’t saturated; it’s warm, hazy, and full of subtle temperature shifts between gold and blue. A restrained, mostly-neutral palette forces those subtle relationships to the surface, where a rainbow of bright colors would flatten them.
Come Build Your Palette With Us
Every pigment here is at our swatching station, waiting for you to test how Lunar Black granulates, how Buff Titanium ages a color, how Indian Yellow glows when you thin it down. Come play and if you want to build a custom late-summer palette tuned to your work (more shadow? more gold? a different granulating black?), that’s one of our very favorite conversations to have.
