Colour perception and measurement

Aims

This module develops an understanding of colour and its reproduction in the context of digital devices.

Learning outcomes

On completion of this module the student will be able to :

• Describe the perceptual attributes of colour and the systems for the representation of colour
• Demonstrate the use of colour measurement instruments and the interpretation of measurement data
• Demonstrate the computation of uniform colour space coordinates from reflectance measurements
• Describe the requirements for consistent colour reproduction across different media.

Indicative content

• Fundamentals of colour: light, surface and observer
• Human colour vision and perception
• Colour rendering to hard copy and displays
• Colour models for digital imaging
• Colorimetry and colour difference
• Evaluating colour measurement instruments
• Uncertainty in colour measurement
• Colour appearance models
• Colour space conversion
• Device-independent colour reproduction

Teaching and learning methods

Lectures and practical workshops

Assessment requirements

This module will be assessed through:

• a comparison of two or more colour imaging devices or colour order systems
• an analysis of the performance of two or more colour measuring instruments.
