15. Blue Ink Dragon Tattoo
For most people, the most authentic dragon is gold. But in some periods of Chinese culture, the blue dragon is also often mentioned. The symbolic meanings of these two different colored dragons are essentially the same.
However, the blue dragon is more widely popular among the people, and the gold dragon is the symbol of the royal family. In other words, if you want to describe an ordinary born hero by the dragon, I think blue is more appropriate.
On the other hand, if you just want to color your dragon, blue is a great option. Because dragons of this color do exist in many cultures and have their own mythology.
Of course, you could use a different color or palette, but make sure it represents your personal style, as it makes more sense.
