Since both flamingo and salmon contain a lot of astaxanthin it would be a good idea to have one of those in the logo. I personally favorize the flamingo. Also the typical color of flamingos/salmons is due to Astaxanthin. So this color could occur in the logo.

The logo is mainly for my website https://www.astaxanthin-ratgeber.com/ and should fit into the upper left of currently green menu. But as I said the menu color will be adapted to the logo color.

The red color used in the website will stay or change only slightly, but the green color currently used in main menu will most probably change and adapt to the logo colors.

A combination of flamingo red and white/creme color is what I think of. But I'm open for other combinations.

The logo can contain either "Astaxanthin Ratgeber" or the domain name www.astaxanthin-ratgeber.com.

Great, thanks a lot! Can only recommend him...
