Dulux Paints, being one of the more popular brands downunder, does not appear in the TFP15 (or later afaik) paint list so I went looking for a way to work out the RGB equivalents.
Going to the main Dulux webpage does not help as they have placed their colour browser inside a flash program embedded in their webpage. However the same does not apply to their mobile phone version
Use your mobile phone browser to go to m.dulux.com.au and browse/search for your colour chips. Make note of the path to those colours, particularly some of the odder colours that only appear in their decorators paint book.
Once you have found the colour, fire up a browser on your pc this time and go to m.dulux.com.au - this wont look very good and navigation is a real pain as the menus are designed for smartphones. However if you have noted the path on your phone, you should be able to navigate to the correct page. eg I was looking for trade only colour called 'Flooded Gum' - a warm grey for some kitchen walls.
its path is:http://m.dulux.com.au/trade/colour/p/PG2/254361/flooded-gum
This will show you a rather large sample of the colour.
Now the trickey bit.
In firefox, right click on the page and select 'view page source'.
In IE, right click on the page and select 'view source'.
This will show you the underlying html used to generate the page. Scan down through the html and look for
<div class="main-colour PG2Specifier" style="background-color: rgb(163,162,159)">
<span style="color: #fff;" >
PG2C3 Flooded Gum
The 3 numbers in the rgb() is the red, green, blue codes you need to enter into a new colour swatch in TFP.
Hope that helps.
ps. many other paint company websites can be used in a similar way to get their RGB codes.
