A colleague recently asked me if it was difficult to mix pigments to match a skin tone.Nope. It may take a little patience, but it's fun and even quite relaxing.Today, I'm going to show you how to match your own skin tone.With a mere 4 components, it is possible to matchhuman skin color &#; from the fairest of fair to the darkest of dark &#; a mere 3 pigments and white are all you need.Those components are pictured above.Sound too easy to be true? How about giving it a try and seeing what you think.Shall we get started?A quick note on measuring spoons.Whether you want to make a small or large portion, use the same measuring spoonfor each color. I wanted only a small-ish portion (enough for a years use), so I used the 'TAD' size of the teensy measuring spoons you see above (equivilant 1.2 ml).Start with very small amounts - much less than you think you might need. The unavoidable process of fine-tuning the color means you will be adding more as you go and your final batch is going to be bigger than expected.Here's how to mix a basic caucasian skin colorThese portions are pictured at the top &#; photographed before fine tuning the mixture to my own skin tone.Because my own skin tone lies somewhere between 'ridiculously fair' and 'ghostly', I had tothe amount of white before I had a match.For very fair skin: add more whiteFor darker skin: add more brownFor very dark skin: add more brown and siennaFor a more yellowish skin tone: add more yellow ochreFor a more reddish skin tone: add more siennaAdd your pigments to your whizzing machine.Whizz until the color is even.Check the colorHere's a peek at my color adjusting process. On the far right (we're reading from right to left in this photo) is a bit of my color mix (I used up my mixture making this ).The first test (/1) was way too dark. But the third try was spot on. As a matter of fact, it was more spot on than my mixture from (which was a titch on the yellow side).When you are happy with the color, transfer it to an air-tight container and LABEL IT with a date.Be sure to clean your whizzing implement. I do this by running it with cornstarch a few times until there is no trace of color left. Carefully remove any remaining powder with a soft brush.That's it!Did you end up with a huge portion of foundation color? No worries! Next time, we're going to take our basic foundation color mixture and use it to make perfectly matched highlighter, blush and shadow-sculpting skin tones.Stay tuned for more make-up making fun!PS: This entire process took me an hour from start to finish. I admit I am practiced, but not that practiced. I only mix foundation colors once a year.

After reading about ferrofluids (liquids with magnetic properties) in MAKE, I started trying to make my own. I learned how to electrolyze water with iron electrodes to create magnetite &#; a jet-black iron-oxide &#; and realized the same process could be used to make simple metal oxide pigments. Instead of just buying supplies at the art store, I wanted to make a painting truly &#;from scratch.&#;
Electrolysis is the process of using direct current to cause a chemical reaction that would not otherwise occur. It requires an electrolyte, 2 electrodes, and a current source. It has many applications, but the most common is probably electroplating, which is used, for example, to coat a large piece of cheaper metal with a small amount of a more expensive one that is more attractive or a
better conductor.
My pigment-making process is dirt simple. The current source is an old cellphone charger with the plug cut off. The electrodes are pieces of common metal hardware, and because they&#;re identical I don&#;t have to pay attention to the current&#;s polarity. The electrolyte is just salt water.

The reaction takes 3 hours and produces a brownish-black mixture of iron oxyhydroxides. It can be repeated with copper electrodes to give a vibrant orange.
This process creates a small amount of hydrochloric acid in the dish. It won&#;t be a lot, but if you keep your hands submerged in it long enough, you could get a rash. It also creates a small amount of chlorine gas, which is poisonous! Work on a small scale in a large, well-ventilated room. Do not attempt to use this process to make large quantities of metal oxides. Finally, it creates large amounts of hydrogen and oxygen gases, which can be explosive if allowed to build up. Again, stick to small scales and work with plenty of ventilation, away from ignition sources.
