Explore the use of colour symbolism in Thomas Hardy's Tess of the D'urbervilles

Red and White are the two main colours used in Hardy's Novel. He utilizes them to represent a number of things , often mixing them to represent change or shifts especially in relation to Tess
RED Red is used in the outset of the book to describe Tess and explore various themes:
Chapter 2: During the Club Walking Tess wears a red ribbon in her hair, this among the white clothes of everyone makes Tess stand out, Hardy singles her out immediately as special or different from the other women.
Chapter 4: Red appears in Prince's Death 'She became splashed from face to skirt with the crimson drops.' In this she is tainted by the guilt of Princes death, perhaps also a foreshadowing of Alec's death.
Chapter 5: Alec is described as having 'full lips, badly moulded though red and smooth', The house is described as of red brick 'like a red geranium' and 'of the same rich crimson colour' as the lodge, which contrasts with the green of surrounding foliage. Red is the colour of the Strawberry's Tess eats, her lips are described as rosy, she is covered in red roses. This use of red represents passion and sexuality in Tess, it reminds us of luxury, blood and lust. The use of fruit and flowers also links to pastoral tradition, Hardy subverts pastoral tradition by linking it with sexuality.
Chapter 47-48: Red is the colour of the threshing machine which becomes an image of hell, danger and evil. It also may represent the anxieties felt by the those in the Victorian era at the wake of the Industrial Revolution, fearful of new technology.
WHITE:
Chapter 2: All the people walking in the club, including Tess are wearing white. This is to represent their purity and innocence, signal that they are chaste
Chapter 11: Before she is raped Tess is wearing a 'white muslin dress' uggesting her innocence and virtue. Her tissue is also described as 'white as snow.'
White is also used at times to continually represents her soul or spirit, despite the loss of her virginity, Tess's job as a milkmaid at Talbothays maintains the association with innocence
