Let us begin with a physics lesson: White light is defined as the complete mixture of all the wavelengths of the visible spectrum. This means that if I have beams of light of all the colours of the rainbow and focus all the colours onto a single spot, the combination of all the colours will result in a beam of white light. [source]
As shown in the picture above, it is possible to create white light in a studio by simply mixing colours.
Question, how do we create colour lights?
Answer, Flash/Strobe Gels!
Question, why do we need create white light on first place?
Answer, BECAUSE we want our subject to have natural human skin colour.
Enough with the science lesson, let us start by creating colourful shadows.
Recipe
Gear we need: minimum of three flashes/strobes ideally of equal power, red green blue gels, and a beautiful model :-p
Place three flashes/strobes next to each other, ideally equidistant.
Put red, green & red gels on each flash
Shoot!
Result
For crisp shadows, use hard light using bare flash/strobe and experiment with height of flash/strobe for different shadow shapes. However, hard light will magnify imperfections on skin so it’s vital that you communicate this to your makeup artist
As you can see in the image above, the last two shadows are below each other; i have achieved this result by lowering the height of 2nd and 3rd strobe, respectively.
You can also experiment with two lights & gels by placing them on either side of model for different effects. However, only using two colours will cause colourcast on your model.
Gear Used/Model
Gear: Canon EOS R with 24-105 F4 L Lens, three Godox V1 Flashes and Godox V-11C color flash gels.
Model: CHANDNI KOUR RANDHAWA
