8 Best Water Mixable Oil Paints in 2026

Thirty-six colors in one box means you can start mixing and matching right away without buying extra tubes. Each 18 ml tube dilutes with water up to 25%, so you get the feel of oil paint without needing harsh solvents for cleanup. That makes this set a natural fit for artists who want a broad palette and easy handling, especially if you’re new to water-mixable oils or working in a shared space where fumes matter.

The trade-off is tube size. At 18 ml each, they hold less paint than the 20 ml tubes in the Holbein Duo Aqua set, so if you work on large canvases or use heavy impasto, you might run through colors faster. But for most studio practice, sketchbook work, and learning color theory, the sheer range of this set gives you more options per dollar than smaller starter packs. It earns its place as a versatile all-around choice.

Ten 1.3 fl oz tubes of professional-grade water-mixable oil paint with high pigmentation and high lightfastness make this set a serious step up for artists who want rich, lasting color without solvent fumes. The paint thins and cleans up with water, so you skip the harsh chemicals while keeping the creamy feel and smooth finish oil painters expect. This pack offers a compact tube format that works for studio sessions and on-the-go creativity.

Ten colors is a limited palette compared to the 36-color Mont Marte set, so you will need to mix more or buy extra tubes for certain subjects. However, each tube is professional-grade with high lightfastness, meaning the paint resists fading over time, important for finished artwork. The Mont Marte set offers more hues out of the box, but the Cobra pack focuses on quality per tube.

The addition of bleached beeswax gives this paint a buttery, smooth body that spreads easily and makes color films less brittle, ideal for artists who want the feel of traditional oil paint without the solvents. With lightfast pigments and a non-toxic, water-thinnable formula, this set suits painters who prioritize both quality and a safer studio environment. The six 20mL tubes offer a focused starter palette for learning or small-scale work.

The Lukas Berlin Pro set comes with just six 20 mL tubes, so you’ll want to grab extra colors or a larger set for big canvases. Compared to the Cobra Artist Oil Colour Value Pack, which gives you ten 1.3 fl oz tubes for more volume and variety, this set prioritizes texture and smoothness over quantity. It feels precise and premium, making it a great choice for detailed studies and mixing practice.

A 10-tube set with 37ml tubes gives you enough paint to explore water-mixable oils without committing to a huge investment. The colors are chosen for versatility. Titanium White, Lemon Yellow, French Ultramarine, and Burnt Umber cover the basics for landscapes, portraits, and still lifes. The paint dries in 5 to 7 days, which is a predictable window for layering or making adjustments. This set is built for beginners who want a real oil painting experience without needing solvents or a dedicated studio space. The buttery texture and consistent color wet or dry are noted in the product description.

The set includes hue replacements for some pigments, such as Cad Red Hue and Alizarin Crimson Hue, rather than the traditional single-pigment versions. If you need paints with high pigmentation and high lightfastness, the Cobra Artist set is an alternative to consider. For a first water-mixable oil set, this Daler Rowney pack offers a versatile palette and reliable performance.

Forty-nine 37ml sticks give you an enormous palette without needing to buy individual tubes, enough to paint portraits, landscapes, florals, or abstract work from one box. Because these are solid oil paints, you get the rich gloss and body of traditional oils, but you can also blend them with water for quick watercolor-like washes. The included stainless steel scraping knife and Colorless Blender expand your techniques further, letting you scrape textures or soften edges. This set suits artists who want a huge color range in a portable stick format that works both as oils and as water-soluble paints.

Sticks require a little prep: you cut off what you need with a knife and gently remove the outer solid oil film before painting. That extra step means it’s not as grab-and-go as tube paints that you squeeze directly onto a palette. If you love having every color at your fingertips and don’t mind the cutting step, this stick set offers unmatched variety in one purchase.

This set includes ten 40 ml tubes of water-mixable oil paint, giving you a range of basic colors for practice and study. The paint handles like traditional oil paint, same brush stroke and minimal color shift over time, but you thin and clean up with water, no solvents needed. Because Cobra Study uses less pigment than the Cobra Artist series, the price stays affordable, making it a practical choice for learning oil techniques without a big investment.

The lower pigment load means the colors are less intense than professional-grade lines like the Cobra Artist set, which has higher pigmentation and lightfastness. If you need maximum vibrancy from the tube, that step up is worth considering. But for daily practice, color mixing exercises, or learning the feel of oil paint without solvent hassle, this set offers good performance at a reasonable cost.

Compared to the Cobra Study Set that gives you 40ml tubes, these 18ml tubes are better suited for sampling or travel than for covering large canvases. The manufacturer recommends diluting with water up to a maximum of 25%, so if you like thin washes you will need to work within that limit. For someone wanting a small, simple oil paint introduction, this set fits the bill.

A 200 ml tube of Titanium White means you can cover big canvases without running out mid-stroke. This is the go-to white for artists who mix their own tints or prime large surfaces, because its opaque body and AA permanence keep your highlights bright and stable over time. It cleans up with water and skips harsh solvents while keeping the same color depth and lightfastness as traditional oils. That makes it a practical pick for anyone who works through white paint quickly and wants a reliable, large-format option.

You get only one color in this tube, so if you are just starting out or want a range of hues, a set like the Cobra Artist Oil Colour Value Pack gives you more variety for the same money. But for artists who already have a palette and burn through white paint, this 200 ml tube saves you from buying multiple smaller tubes. It is a straightforward, no-fuss choice for the painter who values quantity and quality in their most-used color.
