Opacity/Transparency
For Opacity/Transparency, GOLDEN has decided that an eight-point
scale is most appropriate for describing the properties of its
colors. They have assigned each color a number 1 (most opaque,
least transparent to 8 (most transparent, least opaque) to indicate
the relative opacity/transparency of that color.
