This colour is considered “opaque” meaning that the coverage is full, layers underneath are not visible.
This colour is considered “ semi opaque” meaning that the coverage is not entirely full, layers underneath are semi visible.

Four stars indicates that this colour is on the highest end of lightfastness scale; four stars is the maximum.
A pigment is considered to be lightfast, or light stable, if it resists fading over extended exposure to ultraviolet light. A pigment that cannot stand up to direct exposure to UV rays without fading is considered to be fugitive.
The series label indicates the series in which this paint falls within the entire line. For Tri-Art’s Finest Quality High Viscosity and Liquid lines, there are up to 11 series/pricing categories.
The most costly component of any paint is the pigment. Each colour is made up of one or more pigments, coming from a staggering variety of sources. Each of those pigments in turn has gone through a variety of manufacturing processes in order to become a compatible component of the paint. The difference in price reflects the pigment or pigments used and the amount of processing required.
