What to Consider When Buying Acrylic Paint
Eight factors that matter when you're comparing acrylic paint — plus a breakdown of beginner, intermediate, and professional brand tiers.
Student, artist, and professional grade
Acrylic paint comes in three tiers — student, artist, and professional. Student grade has the most filler and variable lightfastness, professional grade uses single-pigment formulas with ASTM-I archival ratings, and artist grade sits between them with rich pigment and consistent colour at a price hobbyists and developing painters can afford.
Chalkola acrylics are artist grade. Our 22 ml tubes carry rich, highly-pigmented formula that blends, mixes, and layers cleanly, and are AP non-toxic + ASTM D-4236 + EN71 certified. Professional acrylics add museum-archive lightfastness and specialty single-pigment ranges (80–200+ colours), but you'll pay 5–10× more per tube.
When to move between tiers: Stick with student grade only for kids' practice or one-off school projects. Move up to artist grade — like Chalkola — as soon as you want your work to look polished and last decades. Move up to professional / single-pigment archival paint only when you start selling, exhibiting, or submitting to juried shows that scrutinise lightfastness.
Tube size
Standard sizes: 22 ml (beginner), 59 ml (intermediate), 120 ml (for large work), 250 ml+ (mural/commercial). Start with 22 ml — enough for 5–10 small paintings per color.
Consistency: heavy body vs. fluid
Heavy body (thick, toothpaste) for traditional painting. Fluid (ink-like) for pouring and fine lines. Most beginners buy heavy body and dilute as needed — it's the most versatile starting point.
Lightfastness rating
Serious paint brands rate each color's resistance to fading under UV: ASTM I (excellent), II (very good), III (fair). For keepsake or gallery work, choose paints rated I or II. Student-grade paints often don't specify, which is fine for practice but not for pieces you want to last.
Color range in the set
A good starter palette includes: 2 reds (one warm, one cool), 2 yellows, 2 blues, 2 browns (burnt sienna, raw umber), 1 green, 1 violet, titanium white, Mars black. Everything else you mix from these 11 colors. Don't overspend on sets with 80+ colors — you'll use 15 of them.
Non-toxic certification
Look for the AP Non-Toxic seal (ACMI) for home and classroom use. Some pigments (cadmium, cobalt, lead-based historical colors) carry CL (cautionary label) warnings — safe to paint with, just don't sand, spray, or eat them. For kids' art, AP-only is the safer choice.
Price per tube vs. value
Cheap paint isn't always a bargain — pigments with heavy filler need 2–3 coats for coverage, which costs more paint overall. Middle-tier artist-grade paint (where Chalkola sits) hits the sweet spot: good pigment load at reasonable prices. Professional single-pigment archival paint costs 3–4× more but lasts on the shelf longer and mixes cleaner.
Brand tradeoffs
| Tier | Price | Best for |
|---|---|---|
| Beginner / artist-grade sets | $20–50 for 32–60 colors | First year of painting, kids' art, daily practice. Chalkola sits here. |
| Intermediate / student-pro line | $50–80 for 24 colors | Year 2–3, developing personal style |
| Professional / single-pigment archival | $150+ for 12 colors | Gallery work, exhibition pieces, archival commissions |
Frequently asked questions
What's the cheapest acrylic paint worth buying?
Chalkola sets in the $20–30 range deliver 32 colors with rich, opaque pigment, AP non-toxic certification, and 22 ml heavy-body tubes. Below $20 for a 32-color set you're usually getting heavily-fillered student paint that won't cover evenly — false economy. Look for 22 ml minimum tube size, AP certification, and a brand that's been on shelves for 5+ years.
How many colors should a starter set have?
24–36 colors is the sweet spot. Fewer than 24 and you're mixing too much from scratch; more than 48 and you're paying for colors you'll rarely use. A 32-color set is the industry standard starter.
What's the difference between student grade and artist grade acrylic paint?
Three differences. (1) Pigment load: artist grade uses higher concentrations of true pigment, so colours are richer and you need fewer coats; student grade uses more filler. (2) Lightfastness: artist grade is rated archival (paintings last 100+ years without fading); student grade can fade in years under sunlight. (3) Mixing behaviour: artist grade mixes cleanly; student grade can muddy when over-mixed. For finished paintings, artist grade is worth the modest price bump.
Are cadmium paints safe?
Cadmium pigments (red, yellow, orange) are classified as potentially toxic if inhaled or ingested. They're safe to paint with — don't eat, sand, or spray them. Modern 'cadmium hue' paints use cadmium-free alternatives that match the color without the warning. Fine for classrooms and home use.
Can I mix different brands of acrylic paint?
Yes — all water-based acrylics mix together regardless of brand. Combining student and artist grade is fine; you just might notice some colors mix smoother than others based on pigment load and additives.
