Example Sentences

"He paints in soot-colours and mud-colours, but, far from enjoying primary hues, has little or no perception of the loveliness of secondary or tertiary colour."

From Project Gutenberg

Russet, the second or middle tertiary colour, is, like citrine, constituted ultimately of the three primaries, red, yellow, and blue; but with this difference—instead of yellow as in citrine, the archeus or predominating colour in russet is red, to which yellow and blue are subordinates.
