I colored with many colors. It can look like its all the same color because I used all similar color Blue but darker or lighter. I put visible layer and used color select tool.

This is Donald trump. I tried to draw like his skin tone which is rough but......

I made layer for each colors. I tried my best to add the brown skin color more smoother by using overlay but did not work out well. I put opacity on my airbrush and color the whole blade and also colored the lines twice. So when I cover it with blue opacity 70 it looks like a blade in movie witch is made of millions of thin lines. I did not know what to do with the pajama pants but I just put softer blue in. Putting softer blue is brightness range.

I colored hiro it looks like he is beaten up i used hard red and soft red .....
