Key Takeaways
-
Watercolor is transparent and takes its whites from bare paper, while gouache carries a white filler and extra pigment that hides whatever sits beneath it.
-
Using watercolor means planning highlights first, then building color in thin layers that dry in minutes, with water alone controlling how pale or strong each wash looks.
-
Gouache is mixed to a creamy consistency and painted in any order, so light shades cover dark ones, though colors shift as they dry.
-
Watercolor wins on cost, portability, and setup, while gouache wins on corrections and flat matte color, so most beginners start with watercolor and add gouache later.
-
Our Tobio's Watercolor Kit includes a 12-pigment palette, paint refills, a cotton paper sketchbook, a water brush, and a wooden palette in one box, so you don't need to buy anything else.
What Separates Gouache From Watercolor
Watercolor is the easier paint to start with, and gouache is only the better pick when you need a specific look. Both are made from the same thing: pigment ground into gum arabic and thinned with water. So the difference between them is not about skill level. Gouache just adds a white filler and more pigment, which stops light from passing through to the paper.
That one difference changes how you work. With watercolor, you have to plan your light areas before you start, because once the paper is covered, you can't add white back in. With gouache, you can fix or paint over anything at any time, but it uses more paint and takes more care to get the brush the right wetness.
At Tobio's Kits, we build complete watercolor sets instead of loose parts, so you skip the shopping step that stops many first paintings before they even begin.

What Watercolor Is & How to Use It
Watercolor is a thin, transparent paint film. Light passes through the pigment and reflects off the paper underneath, which produces the glow associated with the medium.
White paint has no role. Whites and highlights are unpainted paper, so light shapes are marked out mentally or in pencil before painting begins. Color is then built in layers, palest first, with each layer dried before the next is applied.
The working method is short.
-
Wet the brush
-
Lift color from a pan
-
Test the strength on scrap paper, then apply it.
More water produces a paler, looser wash, and less water produces stronger color with tighter edges.
The paint is sold as pans, which are dry cakes that re-wet, or as tubes of soft paste. Pans suit beginners because there is nothing to mix in advance and no setup time before painting. Our Tobio's Watercolor Kit combines the two: twelve refill tubes fill the wells of a pocket palette, and the paint then dries in place and re-wets like a pan.
Watercolor paint is applied in transparent layers from light to dark, using water to control wash strength and edge softness.
What Gouache Is & How to Use It
Gouache uses the same binder with more pigment and an added white filler. The paint sits on the paper's surface rather than showing through, and it dries to a flat, matte finish with no sheen.
Opacity changes the working order. You can lay pale blue over black, cover an error, and lighten colors by mixing in white paint rather than adding water. Painters usually choose it for flat backgrounds, hard edges, and lettering.
This method has one more step than watercolor because you first have to bring the paint to the right thickness.
-
Squeeze the paint onto a palette, or use paint already dried there
-
Add water in small amounts until it reaches a creamy, milk-like consistency
-
Test the mix on scrap paper, since colors shift as they dry
-
Apply in even strokes, largest shapes first and details last
Excess water makes the paint streaky, and thick applications can crack once dry. Darks dry lighter and pale tones dry deeper, so it's better to mix a shade in quantity than match it again later.
Dried gouache re-wets on the palette. The same applies to the painting itself, so a wet brush can lift the layer underneath, and you should apply upper layers quickly with a light hand.
Gouache is an opaque, matte-finish paint that covers underlying layers and requires careful water-to-pigment consistency for even application.
Pros & Cons of Watercolor for Beginners
Most of watercolor's advantages come from its setup, speed, and the small amount of paint each session uses. You can apply it from the first attempt rather than after months of practice.
Pros
-
No mixing or prep, and cleanup is a quick brush rinse.
-
Layers dry in minutes, which makes short sessions workable.
-
Dry pans do not leak or spill, so the kit travels in a bag or pocket.
-
Techniques scale down well, so a small palette and a sketchbook are enough for real practice.
Cons
-
Mistakes are difficult to cover because the paint stays transparent.
-
You have to plan light areas in advance rather than add them later.
-
Water control takes practice, and excess water leaves hard edges or blooms.
-
Strong, saturated color takes several dried layers rather than one pass.
Pros & Cons of Gouache for Beginners
Gouache's advantages follow from its opacity. They matter most to painters who want flat, controlled color.
Pros
-
Covers mistakes and lets you paint light over dark at any stage.
-
Produces even, matte color that scans and photographs cleanly.
-
You can revive leftover paint on the palette and use it in the next session.
-
Sits between watercolor and acrylic if thicker paint is the eventual goal.
Cons
-
Uses more paint per painting, which raises the running cost.
-
Colors shift as they dry, making a mixed shade hard to match later.
-
Thick layers can crack or flake on flexible paper.
-
Lower layers lift when you paint over them with a wet brush.

Starting With Watercolor Using Tobio's Kits
Tobio's Watercolor Kit includes everything beginners need to start painting immediately with no extra supplies required.
Neither paint is more advanced than the other, and both teach the same water control and layering. The decision comes down to the finish you want and how much paint and preparation you are willing to spend to get it. Watercolor asks less on both counts.
We design our kits so a first session needs nothing else on hand. Our Tobio's Watercolor Kit includes 12-pigment refill tubes, a cotton paper sketchbook, a walnut wood palette, and a water brush in one box, with the Beginner Workbook available as a bundle. Shop the kit and start painting today.
Frequently Asked Questions (FAQs)
Can gouache and watercolor be used in the same painting?
Yes. The usual method is to paint the image in transparent watercolor, let it dry completely, then add opaque marks in gouache at the end. Common uses include highlights, pale lines over dark areas, and small corrections.
What is the difference between gouache and acrylic gouache?
Standard gouache uses a gum arabic binder and re-wets after drying. Acrylic gouache uses an acrylic binder and dries permanently, so it cannot be lifted or reworked with water. Acrylic gouache layers more cleanly, and standard gouache is easier to correct.
How do you fix a watercolor mistake?
Wet the area with clean water, wait a few seconds, then lift the pigment with a damp brush, a paper towel, or a clean sponge. Staining pigments lighten rather than disappear. Working in thin layers keeps a painting correctable for longer.
Can dried-out watercolor or gouache be revived?
Watercolor pans are made to dry between sessions and re-wet with a damp brush. Gouache in a tube can harden permanently once air reaches it, though gouache dried on a palette will usually soften again with water.
Is a watercolor kit a sensible gift for someone who has never painted?
It works well as a gift because no prior experience or extra shopping is required, and our kits are suitable for ages 6 and above. A guided option such as our Beginners Workbook removes the blank page, which is the usual reason a first kit goes unused.
*Disclaimer: Tobio's Kits watercolor supplies are designed for ages 6 and above. As with all art materials, paints are not food-safe and should be kept away from the mouth.
