Detailed Description

The BS EN ISO/CIE 11664-5:2024 standard is a pivotal document for anyone involved in the study or application of colorimetry. It provides a detailed explanation of the CIE 1976 L*u*v* colour space, a color space that is widely used in various industries due to its perceptual uniformity. This means that the distance between two colors in this space is proportional to the perceived difference between them, making it an invaluable tool for color matching and quality control.

Additionally, the standard covers the u', v' uniform chromaticity scale diagram, which is a graphical representation of color that allows for easy comparison and analysis. This diagram is particularly useful for visualizing the relationships between different colors and understanding how they interact with each other.

BS EN ISO/CIE 11664-5:2024

This standard BS EN ISO/CIE 11664-5:2024 Colorimetry is classified in these ICS categories:

• 17.180.20 Colours and measurement of light

This document specifies the method of calculating the coordinates of the CIE 1976 L*u*v* colour space including correlates of lightness, chroma, saturation and hue. It includes two methods for calculating Euclidean distances in this space to represent the relative perceived magnitude of colour differences. It also specifies the method of calculating the coordinates of the u?,v? uniform chromaticity scale diagram. This document is applicable to tristimulus values calculated using the colour-matching functions of the CIE 1931 standard colorimetric system or the CIE 1964 standard colorimetric system. This document is applicable for the specification of colour stimuli perceived as belonging to a reflecting or transmitting object, where a three-dimensional space more uniform than tristimulus space is required. This includes self-luminous displays, like computer, television and smart-phone displays, if they are being used to simulate reflecting or transmitting objects and if the stimuli are appropriately normalized. This document, as a whole, does not apply to colour stimuli perceived as belonging to an area that appears to be emitting light as a primary light source or that appears to be specularly reflecting such light. Only the u?,v? uniform chromaticity scale diagram defined in 4.1 and the correlates of hue and saturation defined in 4.3 apply to such colour stimuli.
