The Ultimate Guide to Watercolor Types
Before I get into the nitty-gritty of watercolor types, I suggest you buy the best paint you can afford when you start.
The learning curve is much easier with better quality paint. I’m not just saying that. I’ve been where you are, and I’m a bargain hunter, so I tried to start with cheaper paints.
When the 18-color set is cheaper than the 6-color set, it seems like the better deal. But in the end, you’ll realize that you wasted money and should have bought the nicer set.
Trust me. I have 2! sets of cheap 18-color sets that I hate. The paint cracks in the palettes, the colors are dull and boring and they don’t mix as beautifully as the more expensive sets.
Watercolors consist of pigments, binders, and other stuff. The more pigment, the nicer the colors. Guess what the cheap brands skimp on? Pigments.
Watercolor Types: Pans Vs. Tubes Vs. Liquid Watercolors
Some people say tubes are more vibrant than pan sets, but I don’t see that with quality paint brands.
Please note that all watercolor types can and should be used together for the best color variety and customization.
I have provided links to my favorite sets for convenience.
Watercolor Types: Pan Set
When I first started buying watercolors, I overlooked pan sets, thinking tubes were better. However, watercolor pan sets can be incredibly pigmented. My pan set is now my favorite set!
Watercolor pan sets come in a travel case with the paint in little square boxes or circles. You can also buy individual pans. Water activates the colors. They can be used from the pans or mixed on a palette.
Pros of Pan Sets:
- Portable. This is an excellent feature if you travel a lot or paint outside.
- Ready to go. The colors are ready to be used by just adding water. There’s no squirting out each tube into a mixing palette.
- Inexpensive. For the most part, pan sets are less expensive than tubes or liquids.
- Ready-to-go color palette. If you have trouble making decisions on colors, having a pre-determined color palette can help.
- You can make your own. There are empty pan sets that you can fill with your favorite colors. (Blick link)
- They can be expanded. Most have space to add additional colors.
- Dry faster. (Not the painting, but the set itself.) This can be an important factor if you travel and paint.
Cons of Pan Sets:
- It’s easier to muddy the colors. Unless you’re very diligent about washing your brushes, it’s easier to get the pan set colors dirty.
- Harder to use with big brushes. However, this can be overcome by mixing the colors in a palette.
- Can be hard on brushes. Rubbing your brush into the pans can be tempting to incorporate the water better, but this damages the brush hairs.
Watercolor Types: Tubes
Watercolor tubes look like tiny toothpaste tubes. You dilute the color with water using a palette.
Pros of Tubes:
- It’s easier to find open-stock. Most art supply shops carry tubes, but I have yet to find a local shop that carries individual pans.
- Easy to control how much I use. A tiny dab of paint goes a long way. But if it doesn’t get used, it can be used once it’s dry.
- Can be set in palettes and dried like a pan set. Tube paint can be used in palettes to be more convenient. Water reactivates them with no adverse reaction.
- A little easier to mix. Since you have to have a palette for mixing with water, I find tubes easier to mix since I have more space.
Cons of Tubes:
- Less convenient to use. It takes a few extra seconds to find the color, open it, and squirt it out.
- More expensive. Tubes tend to be more expensive than pans.
- It can dry out.
- Lids can get stuck.

Watercolor Types: Liquid Watercolors
Liquid watercolors come in bottles with eyedroppers. They can be used at full strength or watered down in a palette. (Blick link)
Pros of Liquid Watercolors:
- Brightness. These colors are so bright and add so much depth to a painting.
- Very concentrated. So, a small bottle will last forever because you use a tiny dot.
Cons of Liquid Watercolors:
- Lightfastness. The Dr. Ph Martin colors are made with artificial pigments and will fade in the sun.
- Not easy to reactivate. They can be reused once they dry, but the result is typically a bit gritty.
- More expensive. A set of Dr. Ph Martin’s liquid watercolors is more costly than pans or tubes.
- Stain the paper faster. This can make blending tricky unless you work fast.
- Stain plastic palettes easier. It’s not a deal-breaker, but it’s important to know.

Watercolor Types: Ink
Okay, so technically, ink isn’t watercolor, but it can be used with watercolor for fabulous results, like these amazing textures created by dropping ink on a wet watercolor spot.
Ink comes in a bottle with an eyedropper. It is very pigmented and can be mixed with watercolors or layered over the top as an accent.
I especially love white ink. It’s perfect for adding details to a painting, like stars in the sky.
Some inks can be reactivated with water, so be careful of that. Look for acrylic inks if you don’t want them to reactivate.

Student Grade VS Artist Grade
Student grade is the cheaper version of watercolor paint. It is less expensive because it contains less pigment and more binders.
Artist-grade paint, on the other hand, contains more pigment and fewer binders. This results in paint that is brighter and nicer to work with. I can tell the difference between the two grades when painting.
So which should you choose?
If you’re just dabbling in watercolor and want to make cards for family members, try student-grade paint from reputable brands like Winsor & Newton, Senneilier, or Holbein.
If you plan on taking watercolors seriously, buy the artist grade. You will be much happier in the long run.
Other Considerations for Buying Watercolors
What are you planning to do with your paintings? Do you plan to display them or scan them to work on them digitally?
Watercolor paints have different qualities that make them better suited for certain things.
Lightfastness
Each watercolor paint has a lightfastness number. Lightfastness refers to whether they will fade in the sun or not. The ratings are I, II, III, and IV, with I being the best and IV being the worst.
The rating can be found on the tubes or on the manufacturer’s website. For example, here is the Windsor & Newton information about each color in the Cotman line of tubes.
Colors with low lightfastness must be kept out of sunlight and stored in a dark box or behind glass.
Despite these qualities, I wouldn’t avoid using these colors. These colors are typically vibrant and fun. They’re perfect for scanning into a computer and using digitally.
Fugitive Colors
Fugitive colors refer to colors that fade in the sun. They have the lowest lightfastness rating of IV. Opera Pink is a notorious color known for this property.
To avoid this, look for colors with “new” or “permanent” in the name.
However, I wouldn’t necessarily avoid these colors. They’re better for work that will be scanned or for sketchbook work.
Reflective Qualities
If you plan on scanning your work, it’s also very important to know the reflective qualities of specific paint colors. Metallic and florescent paints, in particular, do not scan well.
For the most part, watercolors scan well, but the transparent parts can be challenging to deal with when there’s a lot of white space.
Gouache is a type of paint you might want to consider if you scan a lot of your work. It’s very similar to watercolor but results in a more opaque finish. The matte quality of the paint is perfect for scanning.
Toxicity
Watercolors contain some pigments and elements that are possibly harmful.
If this is a concern, there are non-toxic versions of watercolors available. There are also cadmium-free versions available from Windsor & Newton.
I have not personally used them, so I don’t know the quality.
What’s the Best Type of Watercolor Paint?
I don’t have a clear preference over which watercolor type is best. I love using all of them together to create my own color combinations.
I suggest playing with all of them and seeing what you like best.
