BCF: Colour-Guidance for Consumers and DIY Users
Ref: G005, Jan 09
General
Users are advised that the actual paint colour from the container might not be identical to that shown on shade cards, brochures or in photographs. The differences can be caused by a number of factors that will result in colour variation, these include different substrates, different level of gloss which will affect the perceived colour, different angle of viewing, the level and type (fluorescent, tungsten, natural daylight etc.) of lighting.
Uniform Colour
A major problem is that people start painting an area and run out of paint, buy more and then notice that the two colours are not exactly the same. This sheet gives some advice and steps to take to avoid this happening. It also includes some information as to why different containers of what is the 'same' colour might look different when applied.
How Much Paint?
To minimise problems of having too little or too much paint it is important to calculate as best you can how much paint you will need.
In-Store Tinted Paint and Ready Mixed Paints
Do not use both ready mixed paints (those already in the container with specified colour) with in-store tinted paints (paints prepared in store using base and tinters). This is because there is always a tolerance in producing any colour and it is likely that when produced in a manufacturing plant it will differ to that made up in a store.
