Why are Light Cabinets grey?

It is a question we are often asked by our customers: Why are light boxes and cabinets grey? Well, we’re going to answer that for you.

In short, grey is not a colour that was decided upon by chance, but because it is uniquely suited to visual assessment.

Here, we’ll reveal further exactly why grey is the colour of choice, rather than the multitude of other colours that are readily available.

You can have any colour as long as its grey – VeriVide (via Henry Ford).

Functional finishes

From the beginning of standardised visual assessment, light cabinets have been a neutral grey colour.

However, as advancements have been made in paint and finishing techniques, so too have the interiors of VeriVide Colour Assessment Cabinets (CAC).

VeriVide currently offers three interior colour finishes, Munsell N5, Munsell N7 and VeriVide 5574.

But why is the colour grey?

To understand why light cabinets are grey, it is important to understand a little bit of the science surrounding colour.

The first attempt at scientific measurement of colour was undertaken by Albert Munsell, who sought to create a ‘rational way to describe color’. His findings have been developed over the past century into the Munsell Color System that is still heavily relied on today.

This system is used to describe colour attributes, in terms of lightness chroma and hue to communicate colour accurately to suppliers’ designers and many others.

VeriVide offer colour training courses to help you better understand and communicate colour throughout your supply chain.

Colour research has revealed that in order to best assess the full spectrum of visible colour, the surrounding area would ideally be completely matt, in the absolute middle of lightness and have a neutral saturation. According to the Munsell Color Space model, this colour is grey.

Part of the reason why neutral grey is chosen is because of a phenomenon known as simultaneous contrast. Simultaneous contrast occurs when two adjacent colours influence how we see them. One colour could become more or less saturated and even the hue can appear different.

This interference with colour perception is disastrous for standardised visual assessment. For example, if you are trying to match a garment to a standard using a cabinet with a red interior, this interior will influence the assessor’s perception of the sample and the standard, causing them to make the wrong decision. 

For suppliers, this can result in fines and loss of contracts, and for retailers and brands, sales can suffer. See this phenomenon for yourself in the image below.

However, neutral colours and particularly grey, do not alter our perception of colour. This makes neutral grey ideal for a light box.

The Munsell color space assigns values to determine how light or dark a colour is. For neutrals, black is 0 and white is 10, denoted N0 and N10 respectively. VeriVide offer two Munsell neutral grey colours of varying lightness, N5 and N7. VeriVide cabinets come with Munsell N5 as standard, which is in the middle of the Color Space. VeriVide also offer the lighter Munsell N7.

From 1964, VeriVide and Marks & Spencer have worked together in creating and updating VeriVide 5574 to create standardised assessment conditions in light boxes throughout their supply chain. The colour is a neutral grey, similar to N5.

Which colour should I choose?

The colour of your cabinet will be determined by a number of factors, such as the industry you serve, who are your clients and the end usage.

It is important that assessment conditions are standardised throughout your supply chain to ensure accuracy and repeatability in results. That means ensuring all light boxes have the same interior colour and the same light sources are used.

Brands or retailers will usually specify a colour that must be used for visual assessment in a lightbox. Typically, N5 is used by most end-users, with N7 associated more closely with American brands and retailers.

Light boxes in N5 and N7 finishes both adhere to ISO 3668 standards. VeriVide 5574 is used by the entire Mark & Spencer textile supply chain and it is also specified by other brands. If you are unsure which colour is right for you, please get in touch.
