Caran d'Ache Watercolor Pencils: Are They Worth the Price?

Two product lines explained

Caran d'Ache makes two distinct watercolor pencil lines, and the difference between them matters. Museum Aquarelle is the premium professional line — 76 colors, harder lead, higher lightfastness ratings across the board. This is the one that gets talked about in professional watercolor circles. Supracolor Soft is their slightly more accessible line, with a softer lead and a wider palette of up to 120 colors.

Both are excellent. Both sit well above mid-range options like Prismacolor or Derwent in pigment quality and wash behavior. The choice between them comes down to working style: Museum Aquarelle rewards precision and detail work; Supracolor Soft is better if you prefer a looser, more expressive approach and want more color options.

For this review I tested both lines in depth. Most of what I say about quality applies to both — I'll flag the specific differences in the comparison section.

Pigment quality: why these are different

When I swatched all 76 Museum Aquarelle colors, the first thing I noticed was that there are no weak spots. No colors that feel like filler or like they were included to pad the count. Even the pale tints, which is where cheaper lines usually cut corners, hold up when wet. The diluted washes still have depth.

Next to Faber-CastellAlbrecht Dürer directly: the pigment density in Caran d'Ache is noticeably higher in most colors. The yellows are brighter, the deep blues richer, and the neutrals have a subtlety that's hard to describe but obvious once you put them side by side. The gap between the two is real. Not night and day, but clearly there.

Supracolor Soft has comparable pigment to Museum Aquarelle in most colors. The main difference you feel is in the lead hardness and dissolution speed, not the pigment output per se.

Water behavior

This is where the difference from everything else becomes obvious. The washes are the smoothest of any watercolor pencil I've tested. A small amount of water dissolves the pigment completely and spreads evenly without resistance or streaking. The pigment doesn't muddy up — even when I layered five or six passes over the same area, the colors stayed clean and distinct.

With cheaper pencils, there's usually a point where additional wet layers start to turn the work grey or muddied. With Museum Aquarelle I never hit that point in normal working conditions. That's partly the pigment quality and partly the precision of the binder formula — both contribute.

Supracolor Soft dissolves a bit faster and spreads more freely, which makes it slightly more forgiving for loose watercolor-style work. Museum Aquarelle requires more intentionality, which I prefer for detailed illustration.

Lightfastness

Lightfastness is where Caran d'Ache pulls away. Most Museum Aquarelle colors are rated IV (excellent) on the Blue Wool scale, the highest standard rating. A small number are rated III (very good). That's the kind of lightfastness you expect from professional-grade watercolor paints, not pencils.

For comparison: Faber-Castell Albrecht Dürer publishes most colors as I or II (their rating system), which is very good. Prismacolor doesn't publish comprehensive data for every color. The gap between Caran d'Ache and the field on this metric is significant.

For botanical illustration, fine art commissions, and any work you plan to sell or display permanently, this matters a lot. Work made with Museum Aquarelle pencils will still look right in 50 years. That's not a guarantee you can make with most other watercolor pencil brands.

Museum Aquarelle vs Supracolor Soft

A direct comparison of the two Caran d'Ache lines:

Museum Aquarelle has a harder lead that holds a sharper point longer, which makes it better for fine detail, hatching, and precise botanical illustration. The lightfastness ratings are the highest in the lineup. The palette runs to 76 colors. It's more expensive.

Supracolor Soft has a softer lead that covers large areas faster and creates broader, more painterly washes with less effort. The palette goes all the way to 120 colors, which matters if you want a wide tonal range without mixing. Lightfastness is excellent but slightly lower than Museum Aquarelle in some colors. The price is somewhat lower.

My personal preference is Museum Aquarelle. The precision suits how I work. But I know painters who prefer the Supracolor Soft because the softer lead feels more like drawing and less like a technical exercise. Both are worth testing if you can get samples before committing to a full set.

The price question

Let's be direct about this. Caran d'Ache Museum Aquarelle costs two to three times more than a Faber-Castell Albrecht Dürer set of comparable size. Faber-Castell is already expensive. So this is genuinely a significant amount of money for something you draw with, and the question of whether the gap is justified is one I think about every time I open the tin.

My answer: yes, but only for the right person. The difference in quality between Caran d'Ache and Faber-Castell is real — I can see it in the washes, feel it in the lead, and measure it in the lightfastness data. But it's incremental, not transformative. Faber-Castell Albrecht Dürer is already exceptional. Caran d'Ache is exceptional plus a bit more.

If you do finished work — botanical illustration, commissions, pieces for sale — the investment makes sense. You'll use these pencils for years, and the lightfastness means the colors will still look right decades from now. If you're a casual hobbyist or still developing your technique, Faber-Castell Albrecht Dürer gives you most of the benefit at a lower price.

The two professional benchmarks. Here is what separates them:

Pick Caran d'Ache for maximum pigment ceiling. Pick Faber-Castell for better cost-per-color and exceptional earth tones.

Pros and cons

What I liked:

• The best wash quality of any watercolor pencil I've tested
• Exceptional lightfastness — most colors rated IV (excellent)
• Consistent pigment density across the entire range, including pale tints
• Clean, non-muddy layering even with multiple wet passes
• Two complementary lines to suit different working styles
• Individual pencil replacements available, so you can replace colors as you use them

What I didn't like:

• The price is genuinely hard to justify unless you're serious about this
• Museum Aquarelle's harder lead takes some adjustment if you're used to softer pencils
• The quality gap over Faber-Castell, while real, is not dramatic enough to make Faber-Castell look bad by comparison
• 76-color range leaves a few specialty hues missing that the 120-color Supracolor covers
