ROSA Gallery Spectrum Watercolour Set –21 Professional Full Pan Colours + Brush, Indigo Metal Tin

Please note – packaging in transition: The photos above include ROSA Gallery's new 2026 tin artwork and a side-by-side comparison with the previous design. Our current shipment from Ukraine has arrived in the classic (previous) tin design shown in that comparison photo, not the brand-new artwork. Everything inside is identical — 21 full pan colours, the mixing palette, the cuvette insert and the brush — only the printed graphics on the outside of the metal case are different. 

If you paint seriously — or you're buying for someone who does — the ROSA Gallery Spectrum 21-Colour Watercolour Set is a genuinely professional palette you can take anywhere. Twenty-eight full pans of highly pigmented, single-pigment-led colour sit inside a sturdy Indigo metal tin (large size), with a built-in brush and mixing palette, so you can go from studio to sketchbook to plein air without repacking a thing.

What's in the tin

• 21 full pan watercolours, 2.5ml each — a broad spectrum from bright cadmiums and pyrrole reds through cobalt and ultramarine blues to earths, greys and a mixing white
• Indigo metal case, large (L) size — durable, water-resistant, with a finger ring underneath so you can hold and paint one-handed outdoors
• Two mixing palette configurations built into the lid, plus a cuvette insert for extra blending space
• Travel brush included — ready to paint straight out of the box
• Pans click securely into the case and can be removed individually for refilling or rearranging your palette
• Made with organic gum arabic and finely ground organic and inorganic pigments

Why ROSA Gallery

ROSA Gallery is a professional watercolour line made in Ukraine, developed with input from working artists at every stage — colour selection, transparency, pigment load and how each shade behaves on paper. The result is paint that's highly pigmented and re-wets easily, with a high proportion of single-pigment colours so your mixes stay clean rather than muddy. Many colours have excellent lightfastness ratings and several granulate beautifully on textured paper. Choosing ROSA also means supporting a Ukrainian manufacturer directly through your purchase.

How artists use this set

The 28-colour range covers everything from botanical illustration and portrait work to landscape and urban sketching, so it works equally well as your main studio palette or as a grab-and-go travel kit. The compact metal tin fits in a bag or rucksack for painting en plein air, on a train, or in a life-drawing class, while the size and colour range are generous enough that many professional artists use it as their everyday working palette at home. It's also a natural next step for a hobbyist ready to move on from student-grade paints.

A gift worth giving

The tin's presentation makes this set an easy gift to get right: it looks and feels like a proper piece of kit straight out of the box, rather than a beginner's set. It suits a watercolourist at any stage — from someone who's just started taking painting seriously to an experienced artist who'll appreciate the pigment quality — and it works for birthdays, Christmas, graduation, or "thank you" gifts for a tutor or mentor.

Delivery & packaging

Orders are carefully packed to protect the metal tin in transit. As noted above, current stock may arrive in ROSA Gallery's previous tin design rather than the new artwork shown in some photos — the paints and contents are unaffected either way. If you have any concerns about which design you'll receive, message us before ordering and we'll confirm current stock.
