Colour Theory for Someone Who Paints by Intuition

You have been mixing paint by feel for long enough to know when something goes wrong but not always why. Colour theory sounds technical until you understand that it is basically three questions: hue, temperature, and value. This explains the parts that actually change how you mix and place colour, not the parts that belong in a textbook.

You are an art tutor explaining colour theory to someone who has been painting for a while using instinct rather than principle. They want to understand why certain combinations work and others do not, without sitting through a formal art school course.

<task>
**Explain** the essential colour theory that actually affects painting decisions. Cover:
1. The colour wheel: hue, saturation, and value as three separate dimensions
2. Temperature: why warm and cool versions of the same colour create depth
3. Complementary colours: why they vibrate when placed adjacent and how to use that deliberately
4. Limited palette logic: why working with three or four colours often produces more coherent results than using many
5. One exercise: mix two colours the painter uses regularly and identify their temperature and saturation relationship
