CAEL1001 Chap.9 Colour as a Visual Language
Colour as a Visual Language
Week 11 treats colour as a visual language rather than as a descriptive tool, asking how the relations between colours do to how a thing is seen, how it feels and how deep it looks, and what colour by itself can build: a pulse, a structure, a meaning. The studio begins by exploring relationships through painted fragments and only then constructs abstract compositions using layering, collage and watercolour.
That order matters: fragments are tested with nothing at stake and can be moved, so you arrive at the composition holding tested pairs rather than intentions.
The chapter separates the four independent variables that the word colour bundles together, shows why most colour problems are value problems in disguise, and covers transparency, where the order of layers is not reversible and a colour therefore carries the history of its own making.
What this chapter covers
- 01
Colour as a language rather than a description
- 02
Choosing colours you like, and why it leaves nothing to say
- 03
Working at full strength everywhere, and the hierarchy it destroys
- 04
Why the studio starts with fragments rather than a composition
- 05
Four independent variables: hue, value, saturation and area
- 06
Most colour problems are value problems, and the test that shows it
- 07
Neighbouring colours change what a colour is
- 08
Holding the composition constant so the interaction is measurable
- 09
Transparency: layer order is not reversible
- 10
Coloured paper as a layer in the stack rather than a background
- 11
Optical movement, and recording it when it happens by accident
Generating a palette from a rule rather than from taste
- 1State the relationship and the proportion before choosing any colour: two neighbouring hues plus one distant hue, at roughly eight to one by area.
- 1Build the fragment set with value varied deliberately within each role, from very dilute to near full strength, and include two painted on coloured stock as controls.
- 1Add one composition constraint that does the structural work: the distant hue may appear once and may not touch an edge.
- 1Let the overlaps generate colours you did not choose, by tearing the upper fragment thin enough to be partly transparent.
Key terms
- Hue
- The colour category itself, such as red or blue, independent of how light, how strong or how large the area is.
- Saturation
- How strong or dilute a colour is. Working everything at full strength removes the hierarchy that lets one area matter more than another.
- Simultaneous contrast
- The effect in which a colour appears to change according to the colours placed around it. Two identical squares on light and dark grounds will not match.
- Transparency
- A layer that lets what is beneath it contribute to the final colour, so the result records the order the layers were made in.
- Optical movement
- The shimmer or vibration produced at the boundary between certain colour pairings at similar values, where the eye cannot settle on a single edge position.
- Colour harmony
- A relationship between colours chosen as a structure for the work rather than as a matter of taste, for example two neighbouring hues set against one distant one.
Colour as a Visual Language FAQ
Why is my colour composition busy and flat at the same time?
Usually because the values sit in a narrow band, so nothing reads as foreground or background and the eye has no route through the sheet. Photograph it and remove the colour: if it goes uniformly mid-grey, the fix is a wider value range within the palette you already have rather than different colours.
How do I choose a palette without just choosing what I like?
Choose the relationship first and the specific colours second. Deciding on two neighbouring hues plus one distant one, in a stated area ratio, fixes the structure before taste gets involved, and it gives your reflection something to be about other than preference.
Does the order I paint layers in matter?
Yes, and it is not reversible. A yellow wash under a blue one does not look like a blue wash under a yellow one, because the first layer has already tinted the light the second modifies. A built colour therefore carries the history of its making in a way a mixed colour does not.
What are the coloured papers for?
They are a layer in the stack, not a backing. Any transparent mark placed on coloured stock has that colour in the mixture, so the same wash on white and on coloured paper gives two different results. Pasting the pair into the diary is a complete experiment in about four minutes.
Assessment move
Paint the fragments first and paint more of them than you think you need, varying value within each hue role so the set carries a range rather than a single strength. Photograph every composition in greyscale before gluing, since that is the only reliable way to see whether the structure is there.
Hold something constant, either the shape of the fragments or the composition itself, so that any effect you observe can be attributed to colour rather than to three things at once. Record accidental optical effects as findings rather than fixing them silently, and bring draft project work to the following week, which is your individual feedback session.
