Note 4 — Chapter VIII

The term "tone," as used here and elsewhere throughout this book, is a word universally employed in art to express varying degrees of lightness and darkness irrespective of colour. The word "shade," as commonly used and accepted, comes nearest to its meaning, but that shade refers rather to varying tint of local colour, as when one says "a beautiful shade of pink." "Shade" is also used to express the reverse of "light," as "light and shade." Objects in nature, when represented in correct relationship of lightness and darkness, are said to be in correct relative tone.
