Working on this gave me the idea that I could do a little tutorial for you guys. I hope this helps you paint portraits, and I'm sorry about how many times you're going to have to look at my face in this post.
The key to painting natural, warm-looking skin is variations in color. This is because
- skin isn't uniform throughout our bodies, and
- skin reflects colors from the environment around it.
The mistake most newbies make is to choose one color for the skin, then use darker and lighter values that same color. This limited palette results in something like this.
It looks like I'm wearing wayyyy too much foundation. Or like I'm wearing artificial android skin. I AM KELLEY BOT. RESISTANCE IS FUTILE.
So how to we bring some life into this freak of nature? We need to add some variation in color to this face - but where do we put those colors?
The colors in people's faces tend to follow a pattern. In general, people tend to have yellow tones on their forehead, the sides of their face, and in the neck. They tend to have pink in the cheeks, nose and ears, blue underneath the eyes, and a bit of blue around the chin.
Let's apply this map to my portrait and see what we get.
Much better. I used a deep clay red on the inside corners of my eyes, and a light pink-lavender for the highlights on my forehead and nose. On my neck, on the right side I used a yellow tone, but on the left side I used a cool blue and grey, because that side of my neck is picking up colors from the background and my blue shirt. Let's compare Kelley Bot vs. Human Kelley one more time:
Now, you don't want to go overboard with this, or else you're going to make your subjects look like they have jaundice and sunburns and five o'clock shadows all at the same time. Getting the right amount of variation in tones, not too much, not too little, takes practice. One way to improve is to be constantly observing the faces of people around you, in tv shows and movies. Caution: observing people's skin tones can be weirdly addictive. Seriously, when I watch movies, I'm only half paying attention to the plot. The other half of my brain is analyzing the actors' skin tones. This is probably why I find a lot of movies hard to understand.
Let's practice on some people who are not me:
So there you have it. Vary up your skin tones, artists. Start observing people's faces. Get distracted during movies. I'm an android.
Now go paint some portraits! I want to see your self-portrait next November 1st. (Or now, if you found this tutorial helpful and you want to show off what you did.)
A lot of what I learned about skin tones comes from Lauren Cannon's excellent Deviantart tutorials on skin tones. Check them out here and here.
