I need help how i donwload this paletts
Hi Grc,
You have :

2 png images as pickers, you right click and save as the images;
put them in the pickers folder:
AmbientDesign/ArtRage2/ Resources/Pickers

you have a reference image that you can save also if you like,
just to remember
but for the color file: right click on the link , normaly a window will appeare to ask you where you will save the file, then download the col file and
after that place it in the color folder that you will find in Resources, next to your pickers folder.

For bigger files you will need a software for downloading, as for example:
Download Accelerator Plus, which have a free version ;
you can find it in here:

I hope I did unswer to your question.
