This is by far my favorite color theory visual I’ve ever worked with.

 

Color theory is often undervalued for coloring services but it comes into play heavily when working on corrective color applications, and even more so when working with fantasy applications.

 

Hairstylists have a pretty easy time explaining to clients the colors used to cancel out undesired undertones, and explaining the benefits of filler for preventing “hollow” colors. It’s harder to explain to clients that they can’t have lavender hair unless it can be made white first or else they’ll just have pastel brown.

 

Colors directly opposite of one another on the color wheel cancel each other out and create shades of brown (shown on the side of the chart). This information can be used to tone hair, or to accentuate tones.

 

The side labeled fillers consists of colors that exist as natural undertones when prelightening hair. If hair is lightened and needs to be dyed a natural shade that is darker then this pigment will need to be refilled first.

 

The side labeled toners is typically used to cancel out underlying pigment after hair is lightened. Green for red, blue for copper, violet for gold.

 

When doing fantasy color applications it’s important to keep this information in mind so you can get the results you’re looking for. Good luck everyone!
