Dulux Colour Mixing

mto

Hi,

Does anyone know how the Dulux colour mixing service works, ie. which colour system they use? I understand its basically a pot of white paint which they then add colour to, so if I went in and specified a particular RGB value, could they mix it even if it isn't one of their standard colours.

Thanks

As I understand it, its the colours in their range from the cards in store. Even if you scan a colour and send it to dulux it's the nearest match in the range.

I took in a pantone chart, and the guy found the nearest dulux colour to it - they won't match pantone and RGB directly, but it helped him a lot to say "Pantone 482c" instead of yellowy green or whatever...

RGB is used for emitted light - eg from a monitor. It can be resolved into other systems susch as Hue Saturation and Lightness - see http://serennu.com/colour/hsltorgb.php

For reflected light, as in printing and painting there is more to it as there is a black component too. Printing tends to use CYMK - Cyan Magenta Yellow Black - and the paint companies use similar schemes.

The Dulux Trade and Leyland Johnstone interactive colour wheels are here http://dulux.trade-decorating.co.uk/colours/ranges/index.jsp and here http://www.johnstonestrade.com/natural-colour-system.aspx In both cases, the number for the colour represents its coordinates in their respective systems.

Both can scan a colour if you can print it - but the match is only generally consistent rather than exact
