Country Flags in Reduced Colors

These 20 country flags have had some of their colors changed to other colors already present in the flag, having the total number of colors in each flag reduced to only 2. As a result of this, some "formats" might have changed. Even then, can you guess each country name?

Nice idea! Maybe accept Norway for the Iceland one?

Thank you! At first, I feel the shades of blue on Norway and Iceland's flags are very different. Put them side by side and I think you'll notice it. Of course, if more people support your suggestion, I'll add the type-in.
