Single-pigment paints from reputable makers, lightfastness rated I or II, and an ACMI AP seal are the three things worth checking before you buy.
One wrong tube can sour a whole first year of painting — a chalky “hue” that dries muddy no matter how carefully you mix it. The label under the wrapper tells you almost everything: whether a color is built from one real pigment or a mix, whether it will fade on the wall, and whether it is safe to handle. The four checks below take about ten minutes in a store and save you from repainting the same swatch forever.
What Should The Label Actually Say?
The label should name the pigment itself, not just a poetic color name. Look for “PB29” or “PV19” style pigment codes and the words “single pigment” — reputable guidance recommends single-pigment paints over imitation “hue” paints or convenience mixtures because they mix more predictably.
Two pigments mixed together behave differently than one pigment pulled toward another hue. A single-pigment ultramarine plus a single-pigment burnt sienna gives you a predictable gray. A convenience green that already contains three pigments turns muddy the moment you add anything else.
Handprint’s color-making notes make the case plainly: the fewer pigments in a tube, the more control the painter has. Manufacturers who print the pigment index name are telling you they have nothing to hide about the formula. If the label only says “Leaf Green” with no code, assume it is a mixture built to hit a color, not a pigment chosen for how it behaves.
How Do You Judge Paint Quality Before You Buy?
Quality comes down to pigment load, lightfastness, and handling — and you can test all three before committing to a full set. Lightfastness ratings of I or II are the standard to look for.
- Reputable guidance recommends testing this yourself by painting a swatch and taping half of it to a sunny window for a few weeks.
- Pigment load: More pigment, less filler.
- Handling: Evaluate how the paint behaves on paper, not just color count.
The most common mistake is choosing by color count — a 36-color set full of weak pigments is worse than a 12-color set of real ones.
Pans Or Tubes: Which Should A Beginner Buy First?
Pans are the simpler start; tubes win once your work gets bigger or you want to refill a palette. Both hold the same paint — the format just changes how you get it onto the brush.
| Format | Best For | Trade-Off |
|---|---|---|
| Pans | Portable sketching and quick practice | Slower to load a large wash |
| Tubes | Large washes and refilling palettes | Waste if you paint rarely |
| Student-grade | First 6 months of learning | Lower pigment load, more filler |
| Artist-grade | Color mixing and finished work | Two to four times the price |
| Single-pigment | Predictable mixing | Fewer colors in a starter set |
| Hue substitutes | Filling gaps cheaply | Can shift or fade over time |
Tube paint can always be squeezed into empty pans later, so nothing is wasted by starting small.

Is Watercolor Paint Safe To Use?
Look for an ACMI seal on the package. ACMI states that AP-labeled products are certified by a toxicologist as non-toxic when used as intended, while CL means cautionary labeling and requires following the package directions.
Older students and adults can generally use CL-labeled products safely by following the warnings on the box. ACMI’s labeling references U.S. standards ASTM D4236, LHAMA, and FHSA, so the seal is a U.S. regulatory-backed mark, not a marketing sticker.
One caveat worth knowing: cadmium and cobalt pigments are genuinely toxic in dry powder form, but bound in watercolor paint they are considered safe for normal handling. Do not sand or scrape dried paint into dust, and never let a child eat the cake.
FAQs
Do I need artist-grade paint to start?
No. Student-grade pans are a fine starting point for the first several months. Move to artist-grade once you are mixing your own colors consistently and want more vibrancy from fewer layers. The pigment behavior matters more than the price tier early on.
How many colors should a beginner set have?
A split-primary set — a warm and cool version of red, yellow, and blue, plus a few earth tones — gives you more mixing range than 36 convenience colors that all lean the same direction.
Can I mix tube paint into pans later?
Yes. Squeeze a small amount into an empty pan, let it dry for a few days, and it rewets like store-bought pan paint. This is why starting with a few tubes and an empty palette is a legitimate path if you plan to work large later.
