The logo must match the existing colors at www.ShopNord.dk.

But you can work around the Astada.com 's suitable colors since they look like my colors a lot. The colors of www.energinord.dk are those I am inspired by (I've even helped to select their logo).

Colors as they are already on www.ShopNord.dk:
#a00028
#ffcc00

Design:
- Possibly think of the logo as ShopNord with the S and N in fat.
- Possibly on the basis of my words: 'tryg, sikker og forsvarlig internethandel' meaning safe, secure, and trustworthy internet business
- Possibly in the style of their own, www.energinord.dk, somewhere in that direction.

The logo must also be displayed in black / gray / white on both light and dark background, so remember that when you design
