LY-Series colours (AKA Layering colours) are a sheer skin tone paint and are a vital part in creating the perfect skin tone finish. LY colours directly correspond to S-series and SFX-series base colours (eg S-301 Light Flesh colour pigment is equivalent to LY-01 Light, S-312 Howie Green colour pigment is equivalent to LY-12 Green, etc...) and this adding a layer of LY colour over top of a layer of F-series or M-series paints will create a perfect "under the skin" look. There are currently 15 colours available:
LY-00 Porcelain (matches S-300 Porcelain)
LY-01 Light (matches S-301 Light)
LY-02 Medium (matches S-302 Medium)
LY-03 Olive (matches S-303 Olive)

LY-Series Silicone Paints
LY-Series paints are sold in 2-part "kits". When using FuseFX paints you mix an equal amount of "Part A" and the chosen colour, then apply as desired to the surface of your cured and clean silicone piece (to prevent loss of details you can also "backpaint" colours into a released mold before filling with the bulk of your silicone).
Each standard bottle "kit" contains a total of 1 oz (30g) of silicone (15g of colour and 15g of part "A") and can cover an area of over 10 square feet when applied in a stipple fashion. A little goes a long way...
You can even custom blend your own colours by combining different colour "parts" before catalyzing with an equal amount of Part "A"!
