ColourPicker Explained

In general we sort colours for products into 2 main groups - ‘Ready Mixed’ and ‘Tinted’.
Tinted colours will always be more expensive than Ready Mixed colours as they need to be produced at the time of order using a tinting machine dispensing colourant into a base*.
During busy periods, this means that tinted colours could take longer, for example – a ready mixed colour ordered on a 3-5 day delivery might arrive within 3 days, however a tinted colour might take the full 5 days to arrive.

To find Ready Mixed colours, search "ready mixed" or select the Ready Mixed 'colour chart'. To see Tinted colours select a colour chart such as RAL, BS, NCS, etc. or search for a colour/hue to see available or related options.

To ensure fair pricing, we split colours into ‘Price Bands’ to group together similar priced colours. If you wish to search for the cheapest tinted colours, always select Price Band 1.

We make every effort to list all available colours, however we also offer a colour match service which can be accessed by contacting our Technical Team on 0113 245 5450 (option 2) or emailing [email protected]

*Colours are sold in the nearest tin size but actual paint volume per tin may vary up to 10% depending on colour

Colour reproduction of the Products on the Site is limited by the technology used to deliver web pages and by the colour representation of Customer’s own monitor and computer set-up.
