My favorite tools

For my start I've chosen the software, which is available for free.
No money spent and high quality got.
So if you want to get the same, I recommend: SketchUp , Kerkythea , Gimp  , MaP Zone

My favorite colour palette is  The Dulux Trade Colour Palette
Dulux products are well-known around the world and are easy to buy almost anywhere.
I like to use the Dulux professional colour range for my basics sketches.
