Buying acrylics online is weirdly easy to mess up. The thumbnails look luscious, the names sound poetic, and two weeks later you’re staring at a stack of tubes that dry darker than expected, fight your brushes, and fade faster than you’d admit to a client.
Here’s the guiding idea I use: judge paint by performance per dollar, not price per tube. Pigment load, pigment identity, and lightfastness will matter long after you’ve forgotten what you paid on sale.
One-line truth: you’re not shopping for “colors,” you’re shopping for chemistry plus handling.
Before you even open a tab: goals + budget (the unsexy part)
If you don’t decide what you’re painting, the internet will decide for you.
Start with the boring questions that save you money:
– What size are you working at most often?
– Which surfaces are you loyal to: canvas, wood panel, paper, mural wall?
– Do you glaze, scumble, paint opaque, or push impasto?
– Are these pieces meant to last decades, or are they studies?
Budgeting isn’t just “I can spend $80.” Split it. I like four buckets: paint / mediums / tools / shipping buffer. That last one matters because online orders punish the unprepared—especially when you shop artist acrylic paints online and discover the freight costs more than the extra tube you forgot.
Now, this won’t apply to everyone, but if you’re still figuring out your style, skip the giant sets and buy small tubes of a few workhorse pigments first. You’ll learn faster, waste less, and you won’t end up hoarding five nearly identical “warm reds” that don’t mix how you expected.
Hot take: if the brand won’t name the pigment, I don’t buy it.
Look, I’m not impressed by “Brilliant Crimson Hue.” I want PB29, PR254, PY150, real pigment codes. If a manufacturer won’t tell you what’s in the tube, you’re gambling on substitutes, fillers, and future reformulations that don’t match.
Lightfastness: the boring rating that decides if your painting survives
Most pro lines give a lightfastness system (ASTM ratings are common). Here’s the practical translation:
– ASTM I: excellent, generally safe for serious work
– ASTM II: very good, usually fine unless it’s in harsh light
– ASTM III+: I treat these as sketchbook-only unless there’s a reason
And yes, lightfastness can vary inside the same line by color. “Brand X is lightfast” is not a useful sentence.
A real-world stat to ground this: The Blue Wool Scale runs 1, 8, and each step represents roughly a doubling of lightfastness (museum conservation literature references this relationship; a commonly cited overview is the Canadian Conservation Institute’s notes on light damage: https://www.canada.ca/en/conservation-institute/services/agents-deterioration/light.html). You don’t need the math day-to-day, but the implication is brutal: a “small” rating difference can mean a lot over time.
Pigment granularity (yes, it changes how you paint)
You can feel it when you’re blending. Some pigments are naturally smooth; others are gritty or “draggy.” Granularity affects:
– coverage and opacity behavior
– how cleanly you can glaze
– how your blends look at the edges (especially in skin tones and skies)
In my experience, beginners often blame themselves for “bad blending” when the real culprit is a pigment that’s coarse, fast-setting, or overloaded with matting agents.
Pigment sourcing + consistency (the grown-up concern)
Here’s the thing: manufacturers don’t all control their pigment supply the same way. Some do tight batch testing; others swap suppliers or tweak formulas quietly. If you sell work, consistency matters. If you repaint series pieces months apart, it matters even more.
I favor brands that publish:
– pigment codes per color
– lightfastness per color
– transparency/opacity symbols
– (ideally) single-pigment options clearly labeled
Acrylic “types” aren’t just marketing, pick the base that matches your habits
Some acrylics feel like butter. Others feel like yogurt. Some behave like ink. Online listings rarely explain this well, so you have to read between the lines.
A quick, practical breakdown
Traditional “heavy body” style paints tend to:
– hold brush marks
– dry fast
– reward decisive strokes
– punish overworking (they’ll lift, tack, or get muddy if you fuss)
More fluid/high-flow acrylics:
– level smoother
– make glazing and pouring easier
– can look streaky if you expect opaque coverage in one pass
Gel/medium-rich systems:
– build texture and volume
– can extend open time depending on medium
– may shift sheen more dramatically across layers
If you’re constantly fighting dry edges, you don’t necessarily need “better paint.” You might need a slower-drying line or a medium strategy that actually suits your climate (dry studios turn acrylic into a speed-run).
One-line emphasis.
Open time is a lifestyle choice.
Brand reputation + color systems: don’t confuse popularity with reliability
A brand’s reputation is only useful if it’s built on documentation and consistency, not influencer buzz. I check three things before I trust a line long-term:
- Do they publish pigment codes and ASTM ratings clearly?
- Do they keep color names consistent across years? (reformulations happen; honesty about them is the tell)
- Do their swatches look like swatches, not cinematic color grading?
Digital color is a liar. Your screen is backlit; acrylic on canvas isn’t. If the retailer offers scanned swatch cards or the brand provides printed reference sheets, that’s a green flag.
Also: color systems matter when you mix. If you care about predictable neutrals, skin tones, or controlled greys, you want pigments that behave consistently, not a rainbow of convenience mixes with mysterious pigment blends.
Sets and value packs: sometimes smart, sometimes a trap
I’m not anti-set. I’m anti-set without scrutiny.
A set is only a deal if the colors match your real mixing habits and the tubes aren’t tiny “tester” sizes dressed up as a bargain. Check for repeat hues. Check pigment info. Check whether half the box is convenience mixes you’ll never repurchase.
A quick test I use: If the set includes more than a couple “Hue” colors with vague pigment info, I skip it. Those are often fillers to inflate the color count.
What’s genuinely useful?
– a primaries + earths starter selection
– a limited palette set designed around single pigments
– a medium bundle that matches your technique (matte/gel/glazing)
If you’re unsure, buy singles first. Then build your own “set” based on what you actually run out of.
Pricing online: do the math or you’ll pay for air
Paint pricing gets sneaky because tube sizes vary and some lines are heavily padded with extender. Normalize prices by cost per ml (or oz), then compare within the same category (heavy body to heavy body, not heavy body to fluid).
Shipping is part of the price. So are returns.
Here’s what I look for in policies:
– Are opened tubes returnable? Usually no, but check.
– Restocking fees? Time windows?
– Do they package liquids properly in winter/summer? (Freezing and overheating can wreck some products.)
And look, if a retailer can’t ship paint without it arriving dented, leaking, or half-crusted at the cap, I don’t “give them another chance.” Paint isn’t cheap enough for that.
Product details that actually change your workflow: re-wettability, drying, open time
Acrylic isn’t watercolor. It doesn’t truly re-wet the same way. But different formulas can feel more forgiving when you mist a palette or use a stay-wet system.
When reading listings and labels, I’m hunting for signals:
– “slow-drying” or “open” acrylics (longer blending window)
– mentions of leveling, viscosity, and film strength
– notes about gloss/matte and how mediums affect it
User reviews can help, but only if they mention process: humidity, surface, layering, brand comparisons. “Great color!” is not a review; it’s a mood.
A practical online buying workflow (the part that saves you from chaos)
I’ve seen artists buy paint like they’re collecting souvenirs. Don’t.
Build a tiny system:
– Keep a running list of staple pigments you always use
– Maintain a simple spreadsheet or notes table: pigment code, lightfastness, transparency, brand, notes
– Reorder staples in batches to reduce shipping costs and avoid “emergency buys” (those are always overpriced)
When trying a new line, do it like a controlled experiment:
- Buy 2, 4 single tubes you know well (a white, a warm red, a blue, an earth)
- Test on your real surface, under your real lighting
- Note drying shift, gloss shift, and mixing behavior
- Then commit, or don’t
That last step is where discipline lives. Most people skip it and blame themselves later.
If you want the shortest version of my advice
Buy fewer colors. Buy better information. Trust pigment codes more than marketing names. And never assume a gorgeous product photo means the paint will behave on your studio table at 10 p.m. when you’re trying to rescue a muddy passage.
