compounds, of whatever tint or shade ; while the
primary colours and the binary compounds, Blue,
Red and Yellow, and Purple, Orange and Green,
are technically distinguished as Colour. The lighter
shades of Tone in this sense are technically
included under the term Greys; warm, as they
contain Orange; cool, as they contain Purple or
Green. Tints and Tones are further classed as
pure, as they approach purple, and those tints
observed in Mother of Pearl, hence, also pearly
tints: warm or hot as they approach Orange:
heavy, and unless they are exceedingly transparent,
muddy as they approach Green.

Half-tints express those gradations of colour,
and half-lights those gradations of light, between
the greatest brilliancy and the shadows.
