Hi people,
As a web designer I found it irritating using multiple programs to create a website and all the graphics associated with it due to the fact I had to keep remembering a million RGB values for each site. I could've made a spreadsheet or even a simple text file, but I decided to go one step further and create a little program for that very purpose. It's perfect for me as I have 2 monitors. It can also do some basic mixing of colours, which is useful. I might eventually replace the very basic Windows colour picker dialog with a custom one, to allow for much better colour mixing, but it does it's job well enough for now.
It only took me about 3-4 days (minus development of the GUI system which has more elements to it than I'm using here) to create the program as it is now. I'm not distributing it at the moment, but if I get some interest in it I might put it on my website.

The GUI is almost 100% drawn using the D3D plugin, with the exception of the arrows on the scrollbar.
The texture button will be a simple tileable texture viewer. I've created some of the code behind this, but I've not integrated it into the app yet. Also I used a set of plugins that use the standard Windows dialog boxes for almost everything other than the main screen.
I've included a screenshot
