how to pick skin colors.
this is a very much simplified method for attaining skin colors, one that i used when i started studying color but no longer need as i can pick color by sight and from memory after much practice. i have tried to keep this simple, but it is still quite complex as color is very complex if you have any questions ask me and i will try to clarify.
you start by picking 3 colors, but this isnt the same method youve heard before. the three colors are not the highlight midtone and shadow colours of the skin but rather the local color and 2 modifiers. using this method you dont actually mix the colours together as in other methods but rather use them as a point of reference to move the marker on the color picker. this makes this method faster and more flexable as you can control saturation. the first modifier is the colour of the main light source, it the example below i use yellow the exact color you pick doesnt matter. the second modifier is the color of the reflected light, below i use blue. the local color of the skin has to be in harmony with the main light source color. i dont have time to explain this now but here is a general rule - if the main light source is yellow the local skin color ( for white skin) will be orange. if the main light source is blue it will be pink, this covers the 2 most common light source colors.
first you need to be familiar with the color triangle.and the correct way to use it. when moving around the color triangle rather than movong in straight lines you need to move in curves.
understanding how colors affect each other.
im not going to cover all colors here but just orange (the color of white skin in yellow light)
adding blue to orange neturaizes it by lowering its saturation.
adding green to orange neturaizes it by lowering its saturation but also makes the hue more yellow.
adding red to orange intensifies it and moves the hue towards red.
adding yellow to orange intensifies it and moves the hue towards yellow.
what youre going to do is create a ramp with the local skin color somewhere in the middle and extending out being affected by the 2 modifiers in opposite directions.
as well as moving toward the modifier you need to change the value , progressively lighter for the main light source and progressively darker for the reflected light again you do not achieve this by mixing the local color with the modifiers but through analitical thinking....
the pattern this ramp makes on the color triangle is a shallow cresent.
its important to note here that once you have the ramp you paint the skin with it, ignoring any other variations you see in color or saturation. this ramp is your values so when painting with it try to imagine it as greyscale. dont try to match what you see just get the values right. that is the next step.once the skin is painted in this imaginary greyscale create a new layer and set the blending mode to color. pick the digital airbrush tool. on the color triangle pick a bright red. then roughly indicate the redder areas by spraying the red color over them- at this stage you must exaggerate it make a very obvious statement, later we will turn down the opacity of the layer to make it more realistic. continue doing this for the whole body and the various colour changes (roughly indicated in the diagram) then change the opacity of the layer until it looks ok.
now finally saturation.
the saturation of your shadows will be determined by what is next to it. the exception to this is your deepest shadow which will always be quite saturated because little reflected light reaches it to lower the saturation. the closer a object is to your skin the more it will influence it. saturation can be added using the photo saturation add brush and can be removed by creating a new layer and changing the blending mode to saturation and painting in grey with the digital airbrush.
flatten your layers and rework it
well hope you find this useful.
i had to leave out many things from this tutourial to keep it simple so it isnt 100% accurate but close enough to create believable skin.
