If you've been working in Chartissimo for a while, the watercolor styles are one of the more unexpected tools in the kit. Soft pigment washes, visible paper grain, hand-painted edges — the kind of look that used to mean hiring an illustrator, available as a one-click style.
This walkthrough covers the watercolor workflow end to end: where to find the styles, when to reach for them, and how to push past the presets with a custom prompt. About three minutes start to finish.
Why watercolor charts work
Watercolor signals "considered." It tells the reader a human paid attention. That's why it shows up in places like:
- Annual reports for foundations, non-profits, and B-corps where the brand reads soft
- Editorial design — magazine features, long-form articles, opinion pieces
- Wellness and lifestyle decks where corporate-blue charts would clash with the visual language
- Pitch decks for consumer brands — beauty, food, hospitality, anywhere "warm" beats "rigorous"
- Education and children's content where playful trumps precise
The aesthetic is hard to fake in Excel or PowerPoint. You'd need to export a chart, open it in Photoshop, paint over fills with watercolor brushes, add a paper texture overlay, and pray the labels still read. Forty-five minutes minimum, every time.
Step 1: Paste your data
Open chartissimo.com/app and paste two or three columns of data into the input panel. Watercolor styles work best with 4–8 categories — busy charts lose the painterly quality.
Step 2: Pick a chart type
Watercolor treatments work with column, bar, pie, and line charts. Pick what your data wants — the painterly look applies to whichever you choose.
- Column or bar — most painterly, the brushwork shows on the bar fills
- Pie — beautiful, like a hand-painted color wheel
- Line — softer than the others; the line takes on a brushed quality
Step 3: Search the style picker for watercolor
In the style picker, search watercolor or browse the artistic styles. You'll see a set of hand-tuned watercolor palettes — cool blues, elegant grayscale, bright primaries, and more. Hover any thumbnail to preview the mood.
If none of the presets match your project's exact palette, skip ahead to Step 5 — the custom prompt path lets you describe any watercolor palette you can imagine.
Step 4: Render the chart
Click the preset thumbnail. The chart re-renders with the watercolor treatment applied to your actual data. The wet-on-wet technique does the work — pigment bleeds softly into adjacent areas, paper grain shows through, edges feather instead of cutting hard.
If the first render is not quite what you wanted, Reroll generates a variation in the same style — different brushstrokes, same palette and mood. The data stays exact across rerolls. Only the painterly treatment changes.
The render uses our depth-aware pipeline, which means the chart geometry stays mathematically correct even as the visual treatment becomes painterly. The bars are the right heights. The pie slices are the right percentages. The watercolor sits on top.
Step 5: Or, paint your own palette with a custom prompt
If none of the three presets match your brand, write a custom prompt. The wet-on-wet watercolor technique works with any palette you describe:
- "Watercolor chart, soft mauve and dusty rose, visible paper grain" — for a foundation or wellness brand
- "Watercolor chart, autumnal burnt sienna and ochre, kraft paper background" — for sustainability reports
- "Watercolor chart, vibrant tropical turquoise and coral, beach-toned paper" — for travel or beverage brands
Lock the seed once you have a render you like — every future chart with that prompt will match. This turns a one-off render into a reusable brand style.
Step 6: Download the PNG
Click Download to save the chart as a PNG. The export keeps the soft-edge bleeds and paper texture intact — drop it straight into your report, slide deck, or article layout.
Tips for getting it right the first time
- Match the palette to the publication. Editorial pieces usually want Grays or Earth. Wellness brands want Pastel. Don't pick Cheerful for a foundation annual report.
- Use white paper backgrounds for print, contextual for digital. The contextual background option adds a stained or aged paper texture that looks great on screen but can muddy in print.
- Lean into fewer categories. Watercolor is at its best with 4–6 data points. Twelve bars in watercolor turn into visual mush — switch to one of our flat presets if your data is dense.
- Save your favorite. Once you've found the palette that fits a recurring project (a quarterly report, a monthly newsletter), save it as a favorite. Every future chart in that project starts one click from on-brand.
The bottom line
A watercolor chart says "we cared about the design" without anyone having to actually paint anything. It's the difference between a report that looks like it was made by an analyst at midnight and one that looks like it was art-directed. Pick the palette that matches the project, paste your data, download. Three minutes.
