Watercolor Painting basics: colour mixing

This is a small site about watercolor painting. Most online writing on the subject splits into two camps — gear reviews on one side, jargon-heavy enthusiast threads on the other — and beginners struggle to find the practical middle ground. The aim here is the opposite: notes that came out of years of painting the boring parts of watercolor painting.

If you are completely new, start with paper choice — that is the foundation that makes the rest easier to learn. Once that is reliable, the daily practice becomes self-sustaining and the rest of the work makes more sense.

Paper Choice

Paper Choice is the part of watercolor painting that gives the most trouble to newcomers, and also the part that improves the fastest with deliberate attention. A few weeks spent on paper choice carefully — rather than rushing to the next thing — usually outperforms months of unfocused practice. The improvement is not glamorous and rarely shows up in a finished result anyone else would notice, but it is what separates a frustrating hobby from a satisfying one.

The rule of thumb: if something feels off and you cannot say why, the answer is almost certainly in paper choice. Slow down, observe, and only change one variable at a time. Keep brief notes if you can. After a few sessions you will start spotting patterns that were invisible at the start, and paper choice will stop being a problem.

Colour Mixing

A useful exercise: write down everything you currently do for colour mixing from memory, without looking anything up. Then do the same thing tomorrow without referring to today's notes. The differences between the two lists tell you which parts of your colour mixing routine are reflexive and which are still being figured out. The reflexive parts are where habits have set; the inconsistent parts are where deliberate attention will pay off.

Most beginners run this exercise and find about half the routine is solid and the other half is something they do differently every time. That is normal — and a clear map of where to focus next. Approach colour mixing with that map in mind for a few weeks and the inconsistent half will steady up.

Common Mistakes

Common Mistakes is the area of watercolor painting where habits form fastest, both good and bad. After three or four sessions of doing common mistakes a particular way, your hands stop thinking about it and the pattern becomes automatic. Re-learning a bad habit later takes weeks. It is worth being a bit careful at the start, even if it slows you down.

The way to be careful is not to be perfect; it is to be consistent. Pick one approach to common mistakes and stick with it for ten sessions before changing anything. If something is not working after ten sessions, then experiment. Switching after every session is the surest way to never get good at any approach.

Paper Choice

Paper Choice comes up sooner than most beginners expect. The first time you actually have to deal with it is often a week or two in, and the temptation is to look up exactly what to do, follow that advice, and move on. The trouble is that paper choice responds to the specifics of your situation more than most other parts of watercolor painting, and generic advice tends to almost work and then slowly stop working.

A more durable approach: understand what paper choice is for, not just what to do about it. Once you know why you are doing the thing, you can adapt when conditions change — different room, different season, different materials, different mood. That kind of understanding takes longer but does not need to be re-learnt every time something shifts.

First Subjects

First Subjects is the part of watercolor painting that gives the most trouble to newcomers, and also the part that improves the fastest with deliberate attention. A few weeks spent on first subjects carefully — rather than rushing to the next thing — usually outperforms months of unfocused practice. The improvement is not glamorous and rarely shows up in a finished result anyone else would notice, but it is what separates a frustrating hobby from a satisfying one.

The rule of thumb: if something feels off and you cannot say why, the answer is almost certainly in first subjects. Slow down, observe, and only change one variable at a time. Keep brief notes if you can. After a few sessions you will start spotting patterns that were invisible at the start, and first subjects will stop being a problem.

Layering

Layering is one of the small areas of watercolor painting where written advice consistently underplays how much variation there is between people. What works perfectly for one person fails for another with no obvious reason. This is not a sign of mystery or talent — it is just that layering interacts with personal habits, environment, and equipment in ways that no general guide can fully cover.

The practical implication: take any specific recipe for layering as a starting point, not a destination. Try it for a few sessions, notice what is and is not working, and adjust deliberately. Within a month or two you will have your own version, which will be better than any generic advice for your situation.

That covers the basics. Beyond this, watercolor painting opens up in different directions for different people — some go deep on common mistakes, some on paper choice, some discover an area not covered here at all. All of those are fine. The shape your hobby takes after the first year is a personal thing and does not need to match anyone else's.
