Colour Charts are an easier way to see the difference in colours. Be aware the colour that have darkened roots may be hard to tell with a swatch. Below are the Jon Renau Colour Charts and take note some of these colours are unique to Jon Renau. A couple things to note:
F – Frosted
H – Highlighted
RH – Rooted and Highlighted
S – Shaded
TT – Two Toned
