Hue: the colour family
Hue is the attribute people usually name first: red, blue, green, yellow, and so on. Changing hue moves a colour around the colour spectrum. When matching colours, hue helps establish whether two colours feel related or deliberately contrasting.
Value: lightness and darkness
Value describes how light or dark a colour appears. A palette with a wide value range is often easier to read because important elements can stand apart. In a user interface, for example, text and its background need sufficient light-dark difference to remain legible.
Saturation: intensity
Saturation describes how vivid or muted a colour appears. Highly saturated colours can feel energetic and attention-grabbing. Lower-saturation colours often feel softer or more understated. Reducing saturation is a useful way to make several different hues feel like they belong together.
Adjust one dimension at a time
When a palette feels wrong, identify the problem before changing everything. If the colours feel unrelated, adjust hue. If the composition lacks hierarchy, adjust value. If the result feels too loud, reduce saturation. This simple diagnostic approach makes colour refinement more deliberate.
Frequently asked questions
What is hue?
Hue is the colour family or position of a colour on a colour spectrum.
Is value the same as brightness?
In everyday design language they are closely related, although technical colour models define lightness and brightness in specific ways.
How do I make a colour less saturated?
Move it towards a more neutral version of itself or adjust its saturation in a colour editor.
