There are no countries with national flags that include red, blue, and pink colors.
Pink is not an official color used in any national flag. Flags typically use bold, easily recognizable colors like red, blue, white, green, black, and yellow. These colors have strong historical and cultural meanings. Because pink is a lighter, less contrasting color, it is rarely used in flags designed for clear visibility and symbolism.
The absence of pink in flags also comes from vexillology, the study of flags, which favors colors that maintain their shade in various lighting conditions and can be clearly seen from a distance. While some flags have colors that might look close to pink—such as certain reds or purples—none officially include pink. For example, the flag of the Bahamas has aquamarine blue and gold, which might be mistaken for soft colors but are not pink.
If you are interested in flags with unusual or pastel colors, explore flags with purple or light blue shades, such as the flag of Dominica or the flags of several Caribbean nations. These categories offer colorful and unique designs without including colors like pink that are not standard in vexillology.
