There are no good colours, only good neighbours
A colour on its own has no qualities worth marking. The same orange is warm against a blue and cool against a red; it is loud in a quiet page and invisible in a loud one; it advances or recedes depending entirely on what you put beside it. Colour is not a property of things. It is a relationship — which is why using more of them makes a page worse, not better.
Why the whole box is the wrong answer
Open a box of twenty-four and the temptation is to justify owning them. It is the single most reliable way to produce a page that reads as brown sludge from three metres.
Here is the mechanism. Every colour you add is a new relationship — not one new thing, but a new relationship with everything already on the page. Two colours make one relationship. Six colours make fifteen. Twelve colours make sixty-six. Past a very small number, you are no longer composing; you are hoping.
And because most colours in a standard box sit at similar saturation and similar value, using them all produces a page with no dominant temperature, no dominant value and no dominant hue — which is the definition of mud. Not because any individual colour was bad. Because none of them was allowed to mean anything.
A limited palette is not a limitation. Three or four colours, used deliberately, will read from across a room. That is what you want: a page that announces itself before anyone walks up to it.
Temperature is the relationship that does the most work
If you only internalise one relationship, make it warm against cool.
Warm colours — reds, oranges, yellows — advance. Cool colours — blues, greens, violets — recede. That is not a rule someone invented; it is roughly how eyes behave, and it means temperature gives you depth for free, without any perspective construction at all.
The practical move: decide a dominant temperature for the page, then break it deliberately in one place. A predominantly cool page with one warm accent has an instant focal point, and the accent does not need to be large — it needs to be alone. A page that is half warm and half cool has an argument rather than a composition.
This pairs with the value lesson: your focal point wants to be the place where the highest value contrast and the temperature break coincide. When those two agree, the eye goes there and nothing else is required. When they disagree, the page pulls in two directions and reads as confused.
Saturation is a resource you can spend once
The third relationship, and the one that separates pages that look considered from pages that look shouted.
Saturation is how intense a colour is. Full-strength pigment straight from the pencil is maximum saturation, and the instinct — especially under time pressure and mild panic — is to use it everywhere, because it feels emphatic.
But saturation only reads as intense in contrast to something less saturated. A page where everything is at full strength has no intensity at all, in the same way a page where everything is dark has no darkness. You have spent the resource and bought nothing.
So treat it as a budget. Most of the page should be muted — greyed, mixed, knocked back. One place should be fully saturated, and that place should be your focal point, and it should agree with your value contrast and your temperature break. Three relationships pointing at the same spot is what a resolved composition actually is, and it is startlingly rare in candidate work.
The good news for a dry medium: muting is easy. Layer a complementary lightly over a colour and it greys immediately. That is thirty seconds of work and it is often the difference between a page that reads and a page that shouts.
The rules behind this
Sourced to the official brochure rather than restated here, so there is one place to correct when the Council revises it.
Part A is three questions: A1 Composition and Colour (25), A2 Sketching and Composition in Black and White (25), A3 3D Composition (30).
Eighty marks across three questions means each is worth roughly 13% of the whole exam. There is no salvaging a bad question by volume, the way a 50-question paper allows.

What almost everyone believes
“Using lots of colours shows range and makes a page more vibrant.”
It makes mud. Vibrancy comes from contrast, and contrast requires most of the page to be quiet.
Colour has no qualities in isolation — only relationships — and every colour added multiplies the relationships you must control. Because standard boxes cluster around similar values and saturations, using them all yields a page with no dominant hue, temperature or value, which reads as brown sludge from a distance. A saturated accent is only intense against muted neighbours, exactly as a dark is only dark against a light. Range is demonstrated by control, not by inventory.
Depending on how long you have
Foundation
Understand the skill. Months out, or starting from zero.
Work with three colours plus the paper, for a month. Any three. The restriction will feel crippling for a week and then it will teach you more about colour than a full box ever could, because you will be forced to make relationships do the work instead of reaching for a new pencil every time something is not working.
Drill
The practice protocol. What to repeat, how often, how to score it.
Before each attempt, write your palette down: three or four colours, a dominant temperature, and where the one saturated accent goes. Then stick to it, even when it gets uncomfortable. Afterwards check whether your value contrast, temperature break and saturation accent all landed in the same place. When they do, you will see it immediately.
Exam-Day
What to actually do under the constraint — 108 seconds, no instruments, one pass.
Pick a dominant temperature in the first minute and commit. Mute most of the page. Save full saturation for one place, and make that place the same place as your darkest dark against your lightest light. Do not open the whole box because you are nervous — that instinct produces mud, reliably, every time.
Try it
Twenty-five minutes. This one tends to change how people see their own work.
- 01Make an A1-style composition using every colour you own. Time it, 25 minutes.
- 02Now make the same composition again using exactly three colours plus the white of the paper.
- 03Pin both up and walk to the far side of the room. Look at them from there.
- 04The three-colour version will almost certainly read better. Note that this is not a matter of taste — it is about which one you can still see from six metres.
- 05Ask which one took less time. It will also be the three-colour version, because you spent no time choosing.
The short version
Colours have no properties, only neighbours. A limited palette reads at a glance; the whole box turns to mud, because every added colour multiplies relationships you cannot control in twenty-five minutes. Choose a dominant temperature and break it once. Mute most of the page and spend full saturation in exactly one place — and make that place agree with your strongest value contrast. When value, temperature and saturation all point at the same spot, the composition is resolved.
Next: assembling all of it under a twenty-five minute clock, which is where the theory either survives or does not.
Questions people actually ask
- How many colours should I use in NATA A1?
- Fewer than you want to. Three or four used deliberately will read from across a room; the whole box produces mud, because standard sets cluster at similar values and saturations so using them all leaves no dominant hue, temperature or value. Vibrancy comes from contrast, which requires most of the page to be quiet.
- What is the fastest way to make a composition read?
- Make your value contrast, temperature break and saturation accent all land in the same place. A predominantly cool, muted page with one warm, fully saturated element at its darkest-against-lightest point has an unmistakable focal point and needs nothing else. Three relationships pointing at one spot is what a resolved composition is.
- How do I mute a colour in dry media?
- Layer its complementary lightly over the top — it greys immediately. It takes seconds and is often the difference between a page that reads and a page that shouts. Muting most of the page is what makes your one saturated accent mean anything.
